Although the panorama is not so diverse as the Unix world, there is
quite a bit of variation on Windows too. Apart from the
cygwin/mingw/vc++ distinction, there are multiple versions of their
respective C libraries, intrinsics and language features supported by
the compilers, etc. Plus some people may want to use third party
libraries for certain things.

Note: the platform tests makes no difference among the official Windows
SDK libraries and MinGW's Winapi. Maybe you are thinking on the MS C
runtime (that evolves with every VC++ compiler release) and the MinGW C
runtime (which wraps some version of the MS C runtime and adds stuff of
its own.)
