mingw-w64

GCC for Windows 64 & 32 bits

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.

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.

I try to add difftime*.o (from v5.04) to libmingex.a manually but linker still doesn't pick it up... I check the buildspecs and can verify that -lmingex came before -lmsvcrt, in v7.0 libmsvcrt.a does have difftime32/64 imports but libmingwex.a should be picked first no? this is gcc 9.3.0 just in case

It has been this way, because actually the WinXP SDK headers had it as LOGFONT, not LOGFONTW (perhaps was an oversight on MS' side), and Vista and newer SDKs changed it to LOGFONTW. Same is the situation with GetThemeFont() you referenced above. I sent a patch to the 'mingw-w64-public' mailing list.
