[Bf-committers] building with opensubdiv using mingw

[Sergey Sharybin]

This is true, but it's not all truth :)

For a long time gcc even from mingw was producing much better assembly than
msvc. Even today msvc requires some annoying poking around with all sort of
weird and wonderful workarounds forbetter performance. Plus it's a bit slow
about all the language extensions and such. From this point of view clang
seems interesting to test.
