+
+ * 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

+
+2017-02-12 Keith Marshall <keithmarshall@users.sourceforge.net>

+ Avoid snprintf() overhead in directory stream functions.
+
+ * mingwex/dirent.c (dirent_update): Do not use either snprintf() or

+
+ 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>

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

+
+2016-10-14 Keith Marshall <keithmarshall@users.sourceforge.net>

+
+2016-10-13 Keith Marshall <keithmarshall@users.sourceforge.net>

+
+2016-09-20 Keith Marshall <keithmarshall@users.sourceforge.net>
+

+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.
+ (AC_PROG_CXX): Identify C++ compiler; the testsuite will use it.
+ (AC_CHECK_PROG): Check availability of autom4te; specify fallback.
+ (AC_CONFIG_FILES): Add instantiation requests for tests/atlocal,
+ tests/Makefile, and tests/testsuite.at.tmp
+
+ * tests/testsuite.at.in tests/atlocal.in tests/headers.at
+ * tests/Makefile.in: New files; implement them.
+
+ * Makefile.in (check, check-recursive, tests): Implement new goals.
+ (mingwrt-srcdist-files): Subdivide package files complement into...
+ (mingwrt-srcdist-package-files): ...this original collection, and...
+ (mingwrt-srcdist-testsuite-files): ...this additional set.
+
+ * test_headers.c: Superseded by autotest; delete it.
+
+2016-08-25 Keith Marshall <keithmarshall@users.sourceforge.net>
+
+ Add pthreads-win32 courtesy support hooks.
+
+ * include/errno.h: Assert copyright; tidy layout.
+ (_ERRNO_H_): Rename this repeat inclusion guard macro as...

+
+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

+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.

+
+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...
+ * Makefile.in ($top_srcdir/../%): ...this symlink dependency rule.
+
+ * 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.
+
+2016-07-17 Keith Marshall <keithmarshall@users.sourceforge.net>
+
+ 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.
+
+ * config.guess config.sub: Delete them; they are no longer required.

+
+ * configure.ac (AC_INIT): Adjust package version number.
+
+2016-07-14 Keith Marshall <keithmarshall@users.sourceforge.net>
+
+ 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)

+
+2016-07-03 Keith Marshall <keithmarshall@users.sourceforge.net>

+
+ * 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
+ convenient shorthand notation for argument declarations in functions
+ 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

+ (_BEGIN_C_DECLS, _END_C_DECLS): Use these.
+
+ * mingwex/tdelete.c: Tidy layout.
+ (tdelete): Reimplement it as a thin wrapper around...
+ (__tdelete): ...this; it encapsulates the original implementation as a
+ __CRT_ALIAS (inline) function, to simplify void ** --> node_t ** casts.
+ Remove unnecessary non-null assertions for arguments #1 and #3; prefer
+ to validate arguments #2 and #3 internally, and simply return NULL if

+
+ * mingwex/tfind.c: Tidy layout.

+ (_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
+ as parameterized templates, providing both -masm-att and -masm-intel
+ syntax implementations, with host specific word size and register
+ assignment parameter substitutions; use them to redefine...
+ (__try1, __except1): ...each of these, using __builtin_alloca to avoid
+ direct stack pushes when registering exception handlers; assign the
+ template parameters as appropriate to support implementation for...
+ [_WIN64, _WIN32]: ...either of these, as the host requires.
+
+2016-06-17 Keith Marshall <keithmarshall@users.sourceforge.net>

+
+2016-05-18 Keith Marshall <keithmarshall@users.sourceforge.net>
+
+ Fix a typo in a <sys/stat.h> inline function definition.
+
+ * include/sys/stat.h [__MSVCRT_VERSION__ >= __MSVCR80_DLL]

+
+ Synchronize package version management with Win32-API.

+
+ * include/string.h [_POSIX_C_SOURCE >= 200809L] (strnlen): Do not

+
+ Make strnlen() available for all MSVCRT.DLL versions.

+
+2016-04-26 Keith Marshall <keithmarshall@users.sourceforge.net>
+
+ Use correct paths for partially included header files.
+
+ * include/io.h include/process.h: Use 'iquote' #include "stdint.h", to

+
+2016-04-11 Keith Marshall <keithmarshall@users.sourceforge.net>
+
+ Eliminate all references to non-standard __NO_ISOCEXT macro.
+
+ * include/math.h: Tidy layout.
+ [!defined __NO_ISOCEXT]: Do not use this ugly double negative; in any
