[PD] Compiling with msys2

[Christof Ressi]

good news: I've just managed to get a working pd.exe + pd.dll with only MinGW and it also works with externals! installing is still a big mess, but that's another story...

I used the makefile.mingw which is lying around in the 'src' folder but I had to change two lines (see the attached diff). this also fixed the ASIO search paths issues for compiling portaudio and it works without a local copy of libstdc++-6.dll.

you have to create an empty 'bin' folder in 'pure-data', then you can cd to 'src' and type

make -f makefile.mingw

pd.exe and pd.dll will show up in pure-data/bin. note that the externals in extra are not being built.

makefile.mingw is independent from autotools but it can be a point of reference.

@Miller: there is no pd.lib involved. you could make one from pd.def and the header files if you want: 
http://www.mingw.org/wiki/MSVC_and_MinGW_DLLs
but where do you actually need it? the only place I can think of is when building externals with MSVC because of implicit linking...
