Add support for MSYS2 based Python

Hello! I am going to compile a helloworld script in MSYS2 on Windows x64. I have installed package mingw-w64-x86_64-python3 and Nuitka from git (I tested 0.6.1 and 0.6.2rc1). When I run python3 -m nuitka test.py --mingw I get: Error, cannot find 'python37m.lib' file. I found this file in MSVC compiled Python’s directory but I can’t use it there. I cannot use MSVC compiled Python because I am going to use a package for Python written in C99 and using some POSIX libraries.

Thanks for help!

@arkdlite I just succeeded in compiling with msys2, and more or less out of the box. It complained about missing crypt.h in the Python header file, so I did this:

pacman -S libcrypt-devel

I already had those, not sure if it’s automatic, or if I had sone those myself:

pacman -Qe | grep gcc
gcc 7.4.0-1
gcc-libs 7.4.0-1

And then this worked:

python bin/nuitka-run tests/basics/Asserts.py

But this one does not right away, although I think this may well have to do with exported symbols from the library, and could be fixable in Nuitka:

python2 bin/nuitka-run tests/basics/Asserts.py

Asserts.build/CompiledCellType.o:CompiledCellType.c:(.rdata$.refptr._PyGC_generation0[.refptr._PyGC_generation0]+0x0): Warnung: undefinierter Verweis auf »_PyGC_generation0«

Also nice, gcc is picked up from PATH automatically, so this is also an easy way to bootstrap things. Now let me check if that Python2 issue is easy to get by.

Yours, Kay

I still got this Error, cannot find 'python37m.lib' file. error using latest MSYS2 and Nuitka 0.6.5. Also installed the above packages. Where can I find this file and where to put it?
