Yes, mingw and VS do not have the same long double type. This has been
the source of some problems in numpy as well, since mingw uses the MS
runtime, and everything involving long double and the runtime is
broken (printf, math library calls). I wish there was a way to disable
this in mingw, but there isn't AFAIK.

I think mostly ABI compatible is the best description :)
