Project Description

MinGW: A native Windows port of the GNU Compiler Collection (GCC), with freely distributable import libraries and header files for building native Windows applications; includes extensions to the MSVC runtime to support C99 functionality. All of MinGW's software will execute on the 64bit Windows platforms.

 2018-02-26  Keith Marshall  <keith@users.osdn.me>

         Prepare and publish MinGW.org WSL-5.1 release.

         * All files (wsl-5.1-release): Tag assigned.

 2018-02-22  Keith Marshall  <keith@users.osdn.me>

         Correct <sys/timeb.h> 32-bit vs. 64-bit time_t anomalies.

         * include/sys/timeb.h: Assert copyright; tidy layout.
         (_TIMEB_H_): Original multiple inclusion guard macro; rename it...
         (_SYS_TIMEB_H): ...conforming to this preferred naming convention.
         (GCC system_header): Add pragma, asserting it as such a header.
         (__need_time_t): Define for selective <sys/types.h> inclusion.
         (_BEGIN_C_DECLS, _END_C_DECLS): Use them as appropriate.
         (pragma pack): Push to pack all structs with 2-byte alignment.
         (struct timeb): Mark as deprecated, from POSIX.1-2001 onwards.
         (ftime): Likewise, mark as deprecated; always emulate it by in-line
         redirection to _ftime(), however this may be implemented.
         (struct __timeb32): Make its definition unconditionally visible.
         (_ftime32) [__MSVCRT_VERSION__ >= __MSVCR80_DLL]: Declare prototype.
         (_ftime32) [_WIN64 || _WIN32_WINNT >= _WIN32_WINNT_VISTA]: Likewise,
         otherwise emulate it by in-line redirection to 32-bit _ftime().
         (struct __timeb64, _ftime64): Make visibility condition symbolic...
         [__MSVCRT_VERSION__ >= __MSVCR61_DLL]: ...thus; add visibility for...
         [_WIN64 || _WIN32_WINNT >= _WIN32_WINNT_WIN2K]: ...these alternatives.
         (_ftime) [__MSVCRT_VERSION__ < __MSVCR80_DLL]: Declare prototype.
         (_ftime) [__MSVCRT_VERSION__ >= __MSVCR80_DLL]: Emulate it...
         [_USE_32BIT_TIME_T]: ...by in-line redirection to _ftime32(), else...
         [!_USE_32BIT_TIME_T]: ...to _ftime64().

         * tests/headers.at [sys/timeb.h]: Suppress "deprecated" warnings.

 2018-02-22  Keith Marshall  <keith@users.osdn.me>

         Correct Windows version support for <utime.h> functions.

         * include/sys/utime.h: Tidy layout; assert copyright.
         (_UTIME_H_): Rename this repeat inclusion guard macro...
         (_SYS_UTIME_H): ...to this, for consistency with current practice.
         (_BEGIN_C_DECLS, _END_C_DECLS): Use them, as appropriate.
         (struct __utimbuf32): Define it unconditionally; remove...
         [__MSVCRT_VERSION__>=0x0800]: ...this prerequisite.
         (_utime32, _wutime32, _futime32): Declare them for...
         [_WIN32_WINNT >= _WIN32_WINNT_VISTA]: ...this, in addition to...
         [__MSVCRT_VERSION__>=__MSVCR80_DLL]: ...this original condition, but
         also emulate them in-line, if neither condition applies.
         [__MSVCRT_VERSION__>=__MSVCR80.DLL] (_utime, _wutime, _futime):
         Implement them in-line, delegating each respectively to...
         [_USE_32BIT_TIME_T] (_utime32, _wutime32, _futime32): ...these, or...
         [!_USE_32BIT_TIME_T] (_utime64, _wutime64, _futime64): ...to these.
         [__MSVCRT_VERSION__>=__MSVCR80.DLL] (utime): Implement in-line, or...
         [__MSVCRT_VERSION__<__MSVCR80.DLL] (utime): ...declare it.

 2018-01-17  Keith Marshall  <keith@users.osdn.me>

         Fix faulty POSIX deprecation warning logic.

         * include/_mingw.h.in (__POSIX_2008_DEPRECATED): Do not nest...
         (__POSIX_2001_DEPRECATED): ...within defininion of this; similarly...
         (__POSIX_1995_DEPRECATED): ...neither within this; rename this as...
         (__POSIX_1996_DEPRECATED): ...this; although conditional upon...
         [_POSIX_C_SOURCE >= 199506L]: ...this, the corresponding standard was
         eventually ratified, not as POSIX.1-1995, but as POSIX.1-1996

 2017-12-28  Keith Marshall  <keith@users.osdn.me>

         Fix a build issue, assembling generic SX files.

         * Makefile.in (%_generic.sx): Always use $(COMPILE.sx) to pre-process
         and assemble these; with $(CC) -c $(ALL_CPPFLAGS) $(ASFLAGS), versions
         of GCC, prior to GCC-4.3, will fail to identify the source file suffix
         correctly, resulting in failure to assemble the code.

 2017-12-18  Keith Marshall  <keith@users.osdn.me>

         Support strtok() re-entrancy, per request [#2342].

         * mingwex/strtok_r.c: New file; it implements...
         (strtok_r): ...this function, per POSIX.1-1995 specification.
         * Makefile.in (libmingwex.a): Add reference; make it depend on...
         (strtok_r.$OBJEXT): ...this.

         * include/string.h: Declare corresponding runtime API.
         [_POSIX_C_SOURCE >= 199506L] (strtok_r): Add function prototype.
         [__MSVCRT_VERSION__ >= __MSVCR80_DLL] (strtok_s): Likewise; this is
         the Microsoft equivalent function, first introduced in this non-free
         MSVC runtime library; subsequently available in MSVCRT.DLL since...
         [_WIN32_WINNT >= _WIN32_WINNT_VISTA]: ...this release, likewise.
 
 2017-12-16  Keith Marshall  <keith@users.osdn.me>

         Implement autotest module for POSIX clock API functions.

         * tests/clockapi.at: New file.
         * tests/testsuite.at.in (clockapi.at): Incorporate it.

 2017-12-15  Keith Marshall  <keith@users.osdn.me>

         Implement a subset of the POSIX.1b-1993 clock API.

         * include/time.h [_POSIX_C_SOURCE >= 199309L]
         (clockid_t): New structured data type; define it opaquely, and...
         (CLOCK_REALTIME, CLOCK_MONOTONIC): ...declare these extern instances.
         (clock_getres, clock_gettime, clock_settime): New functions; declare
         prototypes.

         * mingwex/clockapi.h mingwex/clockapi.c mingwex/clockres.c
         * mingwex/clockset.c mingwex/clocktime.c: New files; they implement
         the preceding clock instances, and associated API functions.

         * include/sys/time.h [_POSIX_C_SOURCE >= 200809L] (gettimeofday):
         Mark it as "deprecated".

 2017-12-14  Keith Marshall  <keith@users.osdn.me>

         Add support for POSIX.1 "obsolescence" warnings.

         * include/_mingwrt.h.in (__POSIX_1995_DEPRECATED)
         (__POSIX_2001_DEPRECATED, __POSIX_2008_DEPRECATED): New macros; define
         them, such as each is conditional on the specific value assigned to...
         [_POSIX_C_SOURCE]: ...this feature test macro, as the equivalent of...
         (__MINGW_ATTRIB_DEPRECATED): ...this, or of nothing, as appropriate.
