+
+ * include/_mingw.h [_ISOC99_SOURCE && __cplusplus >= 201103L]
+ [__GNUC__ < 6] (_GLIBCXX_HAVE_WCSTOF): Define it to 1; it is required
+ because, prior to GCC-6, GCC's configuration process fails to specify
+ it correctly, and so invalidates its own <string> header file.
+
+2017-02-12 Keith Marshall <keithmarshall@users.sourceforge.net>
+

+
+ Ensure selective inclusion of the correct <strings.h>
+

+
+ Avoid -Wformat noise from snprintf() and vsnprintf()

+
+ * mingwex/dirent.c (dirent_update): Do not use either snprintf() or

+ (DIRENT_ASSIGN_NAME): Macro no longer required; delete it.
+ (NUL): New manifest constant; define it.
+
+2017-01-26 Keith Marshall <keithmarshall@users.sourceforge.net>
+
+ Avoid #include_next misbehaviour; cf. MinGW-Bug [#2330]
+
+ * include/ctype.h (wctype.h): Use "..." form of #include, rather than

+
+2017-01-25 Jason Hood <jadoxa@yahoo.com.au>

+
+ * setargv.c [_ISOC99_SOURCE]: Require it.
+ (__mingw32_setargv): Separate command line arguments based on...

+
+2017-01-10 Keith Marshall <keithmarshall@users.sourceforge.net>
+
+ Correct <strings.h> preprocessor logic; fix bug [#2322]
+
+ * include/strings.h (_stricmp, _strnicmp): Always declare, unless...

+
+ * Makefile.in (libmingwex.a): Add x87pow.$OBJEXT
+

+ offers any inline advantage.
+
+2016-11-18 Keith Marshall <keithmarshall@users.sourceforge.net>

+ invalid, in assembly language code.
+
+ * mingwex/math/errno.sx: New file; when included by other assembly

+
+ * mingwex/math/log_generic.sx: New file; it provides a generic back
+ end implementation for multiple logarithmic functions, accessed via...

+
+ * mingwex/math/log1p_generic.sx mingwex/math/log10_generic.sx

+ (log1p, log1pf, log1pl, log10, log10f, log10l, log2, log2f, log2l):
+ ...these functions; thus, they provide complete replacements for...

+
+ * Makefile.in (libmingwex.a): Add dependencies on...
+ (x87cvt.$OBJEXT), x87cvtf.$OBJEXT), x87log.$OBJEXT), x87logf.$OBJEXT):

+ their respective generic sources.
+
+2016-11-08 Keith Marshall <keithmarshall@users.sourceforge.net>
+

+
+ Fix another printf() hex-float formatting bug.
+

+
+ Fix a potentially infinite printf() format conversion loop.
+
+ * mingwex/stdio/pformat.c (__pformat_emit_xfloat)
+ [value.__pformat_fpreg_mantissa == 0]: Do not attempt to normalize

+
+2016-10-14 Keith Marshall <keithmarshall@users.sourceforge.net>
+
+ Add dependency tracking for tests/Makefile.

+
+ * include/string.h [_EMULATE_GLIBC]: Include <strings.h> in full...
+ (strcasecmp, strncasecmp): ...so prototypes for these are declared.
+ [!_EMULATE_GLIBC]: Preserve partial <strings.h> include, guarded by...
+ [__STRING_H_SOURCED__]: ...this context selector, so suppressing the

+
+2016-10-13 Keith Marshall <keithmarshall@users.sourceforge.net>
+
+ Resolve some non-ANSI typedef omissions.
+
+ * include/sys/types.h (off_t, ssize_t): Always typedef them when...
+ [_POSIX_C_SOURCE || !_NO_OLDNAMES]: ...either of these prevails.
+
+ * include/io.h (_fsize_t): Do not suppress its typedef when...
+ [__STRICT_ANSI__]: ...this compiler option applies, irrespective of...
+ [!(_IO_H && _WCHAR_H)]: ...this, which otherwise causes supression.
+
+2016-09-20 Keith Marshall <keithmarshall@users.sourceforge.net>
+
+ Prepare and tag mingwrt-3.22.2 patch release.
+
+ * configure.ac (AC_INIT): Increment patch level.

+ [_ISOC99_SOURCE]: ...this alone.
+
+2016-09-17 Keith Marshall <keithmarshall@users.sourceforge.net>
+
+ Stricter <wchar.h> ISO-C99 conformity filtering.

+
+2016-09-14 Keith Marshall <keithmarshall@users.sourceforge.net>
+
+ Relax strict ISO-C conformity to facilitate C99 support.
+
+ * include/stdlib.h (_atoi64, _exit) [__STRICT_ANSI__]: Convention
+ dictates that the Microsoft specific functions should not be declared;
+ however, C99 provides equivalents in atoll() and _Exit(), for which we
+ gratuituously use them to provide inline implementations; thus...
+ [_ISOC99_SOURCE && !__NO_INLINE__]: ...declare them anyway.
+
+2016-09-13 Keith Marshall <keithmarshall@users.sourceforge.net>
+
+ Suppress expected header warnings when running testsuite.
+
+ * include/dir.h include/dos.h [__IN_MINGWRT_TESTSUITE__]: New feature
+ test; do not emit warning messages, which declare this pair of headers
+ to be obsolete. These warnings are expected, but their format may not
+ be deterministically predictable; there is no reason to fail any test
+ on account of any such expected warning message.
+
+2016-09-13 Keith Marshall <keithmarshall@users.sourceforge.net>
+
+ Create a preliminary autotest framework.
+
+ * configure.ac (AC_TESTDIR): Initialize tests subdirectory.

+
+2016-08-25 Keith Marshall <keithmarshall@users.sourceforge.net>
+
+ Add pthreads-win32 courtesy support hooks.

+2016-08-07 Keith Marshall <keithmarshall@users.sourceforge.net>
+
+ Implement POSIX printf() feature per request [#2310].
+
+ * mingwex/stdio/pformat.c [WITH_XSI_FEATURES]: Delete references.

+ structure member fields; they maintain control state as set up by...
+ (__pformat_enable_thousands_grouping): ...this new internal function.
+ (__pformat_int_bufsiz): Use it; it may request a size increment.
+ (__pformat_emit_digit, __pformat_emit_punct): New functions; they
+ handle output of digits, radix point, and thousands digits separator
+ punctuation for all numeric conversion formats, thus replacing...
+ (__pformat_emit_numeric_value, __pformat_emit_radix_point): ...these;
+ delete them, and update all callers to use appropriate replacements.
+ (__pformat_int) [PFORMAT_GROUPED]: Add and emit group separators.
+ (__pformat_xint_bufsiz): New internal function; it serves in place of
+ __pformat_int_bufsiz(), for those integer data conversion formats
+ which explicitly do not support thousands digits grouping, hence...
+ (__pformat_xint): ...use it, rather than __pformat_int_bufsiz().
+ (__pformat_adjust_for_grouping): New internal function; it adjusts the
+ __gdtoa radix point index for fixed point conversion formats, to allow
+ for the insertion of thousands digits group separators, hence...
+ (__pformat_emit_float): ...use it, and emit separators as appropriate.
+ (__pformat_emit_efloat) [PFORMAT_GROUPED]: Explicitly disable it.
+ (__pformat): Initialise stream references for __pformat_t.grouping,
+ __pformat_t.tslen, and _pformat_t.tschr, on entry; release any memory

+
+ * mingwrt/include/stdio.h [_POSIX_C_SOURCE >= 200809L]

+ * mingwrt/Makefile.in (libmingwex.a): Add getdelim.$OBJEXT
+ (mingwrt-man$man3ext): Add manpage dependency references to create...
+ (getline.$man3ext, getdelim.$man3ext): ...these; declare them as

+ (getline.$man3ext.man): ...this common source.
+
+2016-08-01 Keith Marshall <keithmarshall@users.sourceforge.net>
+
+ Merge mingwrt-3.22.1 legacy updates to 5.0-active branch.
+
+ * mingwex/math/powl.c: Update per issue [#2036] workaround.

+ and subsequent 2016-07-24 optimization.
+
+2016-07-31 Keith Marshall <keithmarshall@users.sourceforge.net>
+
+ Prepare and tag all files for release of mingwrt-3.22.1.

+ patch level identification.
+
+2016-07-31 Keith Marshall <keithmarshall@users.sourceforge.net>
+
+ Interim workaround for issue [#2306].
+
+ * mingwex/math/powl.c: Tidy layout; correct indentation.
+ (powl, reducl): Use ISO-C declaration syntax; K&R is obsolescent.
+ (powl) [OVERFLOW]: Correct representation of return value, using...
+ (INFINITYL): ...this manifest constant value, instead of...
+ (MAXNUML): ...this.
+
+2016-07-24 Keith Marshall <keithmarshall@users.sourceforge.net>
+
+ Optimize printf() field width accumulation function.
+
+ * mingwex/stdio/pformat.c (__imul10plus): Omit multiply by ten on
+ already accumulated zero total; it is unnecessary, since ten times
+ zero is still zero.
+
+2016-07-22 Keith Marshall <keithmarshall@users.sourceforge.net>
+
+ Fix printf() field width parsing regression issue [#2309].
+
+ * mingwex/stdio/pformat.c (__imul10plus): Coerce any accumulated
+ negative total to zero; the only negative value to be handled is...
+ (PFORMAT_IGNORE): ...this; it ceases to be applicable, on first call
+ to __imul10plus(), to accumulate field width or precision.
+
+2016-07-19 Keith Marshall <keithmarshall@users.sourceforge.net>
+
+ Update install-sh to match mingw.org/build-aux package.
+
+ * install-sh: Delete it; use version in parent directory instead,
+ recreating local copy, (as symlink, if supported), on demand.
+
+2016-07-17 Keith Marshall <keithmarshall@users.sourceforge.net>
+
+ Eliminate redundant configuration files.
+
+ * aclocal.m4 VERSION.m4: Delete them; restore them on demand, via...

+
+ * configure.ac (AC_PROG_LN_S): Add configuration check.
+
+2016-07-17 Keith Marshall <keithmarshall@users.sourceforge.net>
+
+ Merge mingwrt-3.22 packaging correction to 5.0-active branch.
+

+
+ Correct mingwrt-3.22 source package subdirectory omission.
+
+ * Makefile.in (mingwrt-srcdist-files): Add msvcrt-xref.
+
+2016-07-16 Keith Marshall <keithmarshall@users.sourceforge.net>
+
+ Discard redundant config.guess and config.sub files.

+
+ Preserve kludge to evade GCC build failure on S_ISBLK misuse.
+
+ * include/sys/stat.h (_NO_UNSUPPORTED): New feature test macro; it
+ should be user defined, if desired, before inclusion; leave undefined.
+ [!_S_IFBLK && !_NO_UNSUPPORTED && !_NO_OLDNAMES] (S_ISBLK): Define it,
+ as appropriate for POSIX conforming usage; do not poison it.
+
+2016-07-10 Keith Marshall <keithmarshall@users.sourceforge.net>
+
+ Fix C++ strict type checking inconsistency in <glob.h>
+
+ * include/glob.h (__ERRFUNC_P): New private macro; define it to match
+ the type signature of the error function pointer, to be passed to...
+ (glob): ...this function; use it to correctly represent error function
+ pointer argument in inline implementation.
+
+2016-07-09 Keith Marshall <keithmarshall@users.sourceforge.net>
+
+ Factor out <ctype.h> vs. <wctype.h> duplicate elements.
+
+ * include/ctype.h: Assert copyright; tidy layout.
+ [!_CTYPE_H_]: Do not evaluate; rename macro to be tested, as...
+ [!_CTYPE_H]: ...this preferred multiple inclusion guard macro name.
+ (__CTYPE_H_SOURCED__): New macro; define it, and include <wctype.h>,
+ so requesting partial inclusion, to retrieve definitions for...
+ (_ALPHA, _BLANK, _CONTROL, _DIGIT, _HEX, _LOWER, _PUNCT, _SPACE)
+ (_UPPER, WEOF): ...these macros; hence, do not define them locally.

+
+ Do not pass MAKEFLAGS explicitly, when invoking recursive make.
+
+ * Makefile.in (install-strip, uninstall): Delete explicit $(MAKEFLAGS)

+
+ * include/search.h: Assert copyright; tidy layout.
+ (_SEARCH_H_): Rename this multiple inclusion guard macro...
+ (_SEARCH_H): ...to conform to this preferred standard convention.
+ (__search_comparator): New function prototype typedef; it provides a

+ which require a comparator function pointer; use it where appropriate.
+ (tsearch, tfind, tdelete) [__MINGW_ATTRIB_NONNULL]: Apply to arguments
+ #2 and #3; was previously incorrectly applied to arguments #1 and #3.
+ (twalk) [__MINGW_ATTRIB_NONNULL]: Apply to both arguments #1 and #2.
+ [_SEARCH_PRIVATE] (__MINGW_ATTRIB_NONNULL): Suppress its effect, to

+
+ * mingwex/tdelete.c: Tidy layout.
+ (tdelete): Reimplement it as a thin wrapper around...
+ (__tdelete): ...this; it encapsulates the original implementation as a

+ Remove unnecessary non-null assertions for arguments #1 and #3; prefer
+ to validate arguments #2 and #3 internally, and simply return NULL if

+ (_BEGIN_C_DECLS, _END_C_DECLS): Use these.
+ (__typecast_alloca): New macro; define it, casting return type of...
+ (__builtin_alloca): ...this to a specified data type; use it in...
+ (__try1_setup, __except1_teardown): ...these new macros; define them

+ (__try1, __except1): ...each of these, using __builtin_alloca to avoid

+
+2016-05-18 Keith Marshall <keithmarshall@users.sourceforge.net>
+
+ Fix a typo in a <sys/stat.h> inline function definition.
+

+
+ Synchronize package version management with Win32-API.

+ * Makefile.in (libmingwex.a): Add requirement for...
+ (strnlen.$OBJEXT): ...this; add vpath specification for its source.

+
+ Use correct paths for partially included header files.
+
+ * include/io.h include/process.h: Use 'iquote' #include "stdint.h", to
+ ensure that we get stdint.h from the same include directory.
+ * include/stdio.h: Likewise for #include "stdarg.h", and "sys/types.h"
+ * include/wchar.h: Likewise for all of #include "stdio.h", "stdlib.h",
+ "direct.h", "sys/stat.h", "io.h", "time.h", "locale.h", and "process.h"
+ * include/dir.h include/dos.h: Likewise for #include "io.h"
+ * include/direct.h: Likewise for #include "dos.h"

Generalize procedure for installing manpages.
[__need_ssize_t, __need_time_t]: Move corresponding #undef out of, and
after the respective conditional blocks, which provide each associated
typedef, so ensuring that any repeat request is properly reset.
-
+
* include/time.h [__need_time_t]: Always delegate to <sys/types.h> for
typedef, and reset of request, even in cases where...
[_TIME_H]: ...this is already defined.
* jamfile: Delete it; it hasn't been updated in ages, is likely no
longer relevant, and I have no desire to maintain it.
+2012-08-02 Earnie Boyd <earnie@users.sourceforge.net>
+
+ Add another more rigorous __STRICT_ANSI__ filter.
+
+ * include/limits.h [__STRICT_ANSI__] (PATH_MAX): Suppress definition.
+ * include/sys/param.h [PATH_MAX defined] (MAXPATHLEN): Alias it.
+ [PATH_MAX not defined] (MAXPATHLEN): Define it directly.
+
+2012-08-02 Ivan Maidanski <ivmai@users.sourceforge.net>
+
+ Add missing function prototypes per issue [#1305].
+
+ * include/process.h [#ifndef _WPROCESS_DEFINED]
+ (_wexecl, _wexecle, _wexeclp, _wexeclpe, _wexecv, _wexecve)
+ (_wexecvp, _wexecvpe, _wspawnl, _wspawnle, _wspawnlp, _wspawnlpe)
+ (_wspawnv, _wspawnve, _wspawnvp, _wspawnvpe): Declare them.
+
+2012-08-02 Earnie Boyd <earnie@users.sourceforge.net>
+
+ Add function prototype declarations per issue [#1293].
+
+ * include/stdio.h (_lock_file, _unlock_file): Declare them.
+
+2012-08-02 Earnie Boyd <earnie@users.sourceforge.net>
+
+ Apply some more rigorous __STRICT_ANSI__ filtering.
+
+ * include/stdio.h (_getws, _putws, _wfdopen, _wfopen)
+ (_wfreopen, _wfsopen, _wtmpnam, _wtempnam, _wrename, _wremove)
+ (_wperror, _wpopen): Do not declare these functions unless...
+ [#ifndef __STRICT_ANSI__]: ...this is satisfied.
+
+2012-08-02 Earnie Boyd <earnie@users.sourceforge.net>
+
+ Add string to 64-bit integer conversion function prototypes.
+
+ * include/stdlib.h (_strtoi64, _strtoi64_l, _strtoui64, _strtoui64_l)
+ (_wcstoi64, _wcstoi64_l, _wcstoui64, _wcstoui64_l): Declare them.
+ * include/wchar.h (_wcstoi64, _wcstoi64_l, _wcstoui64, _wcstoui64_l):
+ Likewise; these are duplicates of the <stdlib.h> declarations.
+
+2012-08-01 Earnie Boyd <earnie@users.sourceforge.net>
+
+ Update for _WIN64 exception handler readiness.
+
+ * include/excpt.h [_WIN64] (__try1, __except1): Add alternative inline
+ assembly code implementation, based on X86-64 architecture.
+
+2012-07-30 Earnie Boyd <earnie@users.sourceforge.net>
+
+ Correct missing inclusion of <_mingw.h>.
+
+ * include/stdint.h: Add omitted #include; all mingwrt headers are
+ expected to include this; it is required to define __int64.
+
+2011-11-30 Ozkan Sezer <sezero@users.sourceforge.net>
+
+ Correct prototypes for _wfindfirst()/_wfindnext() function family.
+
+ * include/io.h (_wfindfirst, _wfindfirst32, _wfindfirsti64)
+ (_wfindfirst32i64, _wfindfirst64i32): Return type changed to intptr_t.
+ (_wfindnext, _wfindnext32, _wfindnexti64, _wfindnext32i64)
+ (_wfindnext64i32, _wfindnext64): Type of parameter #1 must match.
+
+2011-11-30 Earnie Boyd <earnie@users.sourceforge.net>
+
+ Avoid potential GCC "missing function prototype" warnings.
+
+ * include/stdio.h (getc, putc, getchar, putchar, fopen64)
+ (ftello64): Provide a function prototype declaration for each of
+ these, prior to the corresponding inline implementation.
+
2011-08-23 Chris Sutcliffe <ir0nh34d@users.sourceforge.net>
* include/_mingw.h: Increment version to 3.20.
