Not always. mingw32 is still based on msvcrt6. You can make it link against
msvcr7 to match the runtime of Python, but many of the implementations of the
standard C headers are still intended for msvcrt6. C++ extensions using
std::iostreams are vulnerable to segfaults if you reconfigure mingw32's specs
file to only use msvcr7. Other extensions that pass FILE* pointers between them
and Python will segfault if you don't reconfigure mingw32. There is no
configuration of mingw32 that works for all extensions.
The default is the default because it's the only one that's known to be safe.
