Mingw32 port uses only the multithreaded runtime (either CRTDLL or MSVCRT),
so -MT and -MD is implicit (ie., -MD -MT is on by default).

Currently, the C++ runtime is not thread-safe, but I'm planning to release
a runtime update soon that will fix that problem.

Currently, for both Cygwin and Mingw, you need to add -mwindows when 
linking, which provides a few extra libraries and also changes the entry 
point for Mingw32. 
  
  $ gcc -mno-cygwin -o foo.exe foo.c -v -mwindows 

to see what happens.

Regards,
Mumit
