If you allow me to share my experience in the LyX project WRT mingw/msys 
versus MSVC: We tried very hard to use it, but at the end we faced many 
issues, so many issues that MSVC was the only pragmatic choice:
- autotools hell with msys: the automake version was simply too old and 
we had to mix cygwin and msys environment to get something done.
- linker hell: more than 500 megs of RAM was needed to link LyX with 
Qt3, the situation was better with Qt4 but still.
- compilation slowness. Mingw is just not good with C++.
- binary slowness: this is less of a problem with Qt4 but still, the 
MSVC compiled LyX is much faster.

In conclusion, I guess C-compilation is fine with Mingw and you should 
definitly stay with it for git, but for a heavy GUI oriented C++ program 
I strongly recommend MSVC.
