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.

I've been struggling with building on Cygwin (That is, using the Cygwin shell, gcc + binutils). I've been having trouble with missing headers but by descending into subdirectories and makeing there, and I've successfully built the crt lib/w32api etc. But now so I have to build a native compiler using this? Also, binutils and gcc were not built and installed. This is a very complex project! I've been away from computing for several years and I am overwhelmed.

That's because that toolchain was not built with dwarf2. Use SEH instead.

I downloaded MinGW via HomeBrew and there is no libgcc_s_dw2.dll file in folder. I really need it and can you tell me what to do to get it. Also there is no make file.
