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 8 has been released

v8.0.0: 2020-09-18

Notable changes:

New Hyper-V headers and libraries by Biswapriyo Nath
Many headers updated from Wine by Jacek Caban.
ARM math improvements by Martin Storsjö
floating point fixes by Liu Hao
many *printf compatibility fixes by Liu Hao and Martin Storsjö
massive Windows App Store API updates by Steve Lhomme
winstorecompat library updates by Martin Storsjö
__USE_MINGW_ANSI_STDIO now automatically enabled in C99 and C11 mode when not using UCRT by Pali Rohár
wdm and ddk updates by Zebediah Figura

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.

i think you should have made that left turn at Albuquerque...this is for development of gcc compatibility for windows
