Mingw-w64
Mingw-w64 is an advancement of the original mingw.org project, created to support the GCC compiler on Windows systems. It has forked it in 2007 in order to provide support for 64 bits and new APIs. It has since then gained widespread use and distribution.
The development and community are very active and welcoming with new contributors every month and simple installers.
Version 4.0 has been released
- 32bit ARM thumb software math (Thanks to André Hentschel!).
- New ftw() support for gcc-5.x support.
- Experimental printf changes - Ability to print 128bit integers (%I128*) and Decimal Floats (%H, %D), disabled by default. Build the CRT with —-enable-experimental to use.
- Updated OpenGL 4.5 headers.
- Better DirectX 11 support.
- Better Windows 7, 8/8.1 API support.
You can also look at the full list of versions.
Headers, Libraries and Runtime
- More than a million lines of headers are provided, not counting generated ones, and regularly expanded to track new Windows APIs.
- Everything needed for linking and running your code on Windows.
- Winpthreads, a pthreads library for C++11 threading support and simple integration with existing project.
- Winstorecompat, a work-in-progress convenience library that eases conformance with the Windows Store.
- Better-conforming and faster math support compared to Visual Studio's.
Tools
- gendef: generate Visual Studio .def files from .dll files.
- genidl: generate .idl files from .dll files.
- widl: compile .idl files.

Where can I download a version with this fix? I've tried MinGW-W64 GCC-8.1.0 - x86_64-posix-seh from https://sourceforge.net/projects/mingw-w64/files/ with no luck. Also Tried the TDM-GCC 9.2.0 and Nuwen MinGW64 9.2.0 both built from Mingw64. Also. I updated my code to #undef STRICT_ANSI and manually call _fpreset(); ( https://pastebin.com/NE8D0DVb ) and this seems to work perfectly. Super hacky though, but will be sufficient enough to allow me to get correct results until a fix is available. Note:...

I believe this issue has been fixed by https://sourceforge.net/p/mingw-w64/mingw-w64/ci/295fafcf584ce105426045b03d17aa90d105808d/ (which should be part of the mingw-w64 v8.0.0 release). That commit fixes it for pthreads (and std::threads with libstdc++), but won't fix it if manually creating threads or using libc++ yet though.
