     - should be also available in common distros as cross-compiler


In Ubuntu 12.04 we have this:
$ apt-cache search mingw
gcc-mingw-w64-i686 - GNU C compiler for MinGW-w64 targeting Win32
gcc-mingw-w64-x86-64 - GNU C compiler for MinGW-w64 targeting Win64
gcc-mingw32 - GNU Compiler Collection for MinGW32 (transition package)

I assume gcc-mingw32 is the official mingw32, it is only 32bit.

Fedora uses mingw-w64:
https://fedoraproject.org/wiki/MinGW/CrossCompilerFramework

So I would say mingw-w64 is the choice.

And if the Windows mingw-w64 setup misses some features we
should ask if this could be changed by the mingw-w64 project.
