+
+ Correct quoted backslash handling, per bug [#2328].
+

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

+
+ * 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
+ declarations of those function prototypes.
+
+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.

+2016-09-17 Keith Marshall <keithmarshall@users.sourceforge.net>
+
+ Stricter <wchar.h> ISO-C99 conformity filtering.

+
+ 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

+ 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.
+

+
+2016-08-25 Keith Marshall <keithmarshall@users.sourceforge.net>
+

+
+ Implement POSIX printf() feature per request [#2310].
+
+ * mingwex/stdio/pformat.c [WITH_XSI_FEATURES]: Delete references.

+ appeared in an occluded XSI feature reference, but is now required.
+ (__pformat_t.tslen, __pformat_t.tschr, __pformat_t.grouping): New
+ 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>
+
+ Implement POSIX conforming getline() and getdelim() functions.
+
+ * mingwrt/mingwex/stdio/getdelim.c: New file.

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

+ inline, with __LIBIMPL__ external representation.
+
+ * 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>
+

+ * 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.

Preserve kludge to evade GCC build failure on S_ISBLK misuse.
2016-05-12 Keith Marshall <keithmarshall@users.sourceforge.net>
+ Synchronize package version management with Win32-API.
+
+ * VERSION.m4: New file; link it to keep in sync with identically named

+
+ * aclocal.m4: Link it, to keep in sync with identically named files in
+ top level composite source and sibling w32api sub-package directories.
+ (__VERSION__): New macro; include VERSION.m4 to define it.
+ (__BUG_REPORT_URL__): New macro; define it.
+
+ * configure.ac (AC_INIT): Assign package version and bug report URL...

+
+2016-05-12 Keith Marshall <keithmarshall@users.sourceforge.net>
+
Resolve some strnlen() implementation issues.
* mingwex/strnlen.s (__mingw_strnlen) [!NUL]: Correct termination
[__need_ssize_t, __need_time_t]: Move corresponding #undef out of, and
