In this commit i've fixed crash when opening file browser. This crash was caused
by different _stat structures size in storage.c and filelist.c (because of force
setting __MSVCRT_VERSION__ in storage.c), other errors from report
were fixed earlier.
I've used _stati64 strcutrure and functions and tested on official
mingw-gcc 3.4.5, official mingw-gcc 4.4.0, tdm-mingw-gcc 4.4.1,
cross mingw-gcc 4.4.4 and cross mingw-gcc 4.2.1-sjlj -- everything was
ok in this configurations (except openexr and opencollada libraries which
requires sjlj compiler, so i was unable to build blender with that
libraries by official mingw-gcc 4.4.0)
