This is the official download site for the latest packages originating from the MinGW.OSDN Project, (formerly the MinGW.org Project; however, that domain is no longer associated with this project).
MinGW is 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. Although (currently) offering only a 32-bit compiler suite, all of MinGW's software will execute on the 64bit Windows platforms.

Changes introduced since the previous (version 5.0.2) release are:
Fork 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.
