- remove scons option WITH_BF_FHS, its not needed anymore.
- comment WITH_BF_DOCS, was using epydocs which we dont use now.
- blenderlite target was broken, always using openmp.
- building without python wasnt working.
- fixed some warnings.
- Reverted own changes made to _stat function BLI_exists
- Use __MINGW32__ instead of FREE_WINDOWS in BLI_exists
- Removed recently added lib dependencies for mingw
- Use _stat64i32 instead of _stat in BLI_exist
Needed for correct compilation by mingw, no sense for msvc
(_stat is equivalent to _stat64i32 in Visual C++ 2005, and later i suppose)
- Added library msvcr90 for mingw to solve linking error to _stat64i32
