In my initial attached patch I used scons to build osmesa for Windows:
"scons platform=windows toolchain=crossmingw machine=x86 osmesa"

Is there a reason to not use scons? And just for the record: For
GNU/Linux I used:

 ./configure \
   CXXFLAGS="-O2 -g -DDEFAULT_SOFTWARE_DEPTH_BITS=31" \
   CFLAGS="-O2 -g -DDEFAULT_SOFTWARE_DEPTH_BITS=31" \
   --disable-xvmc \
   --disable-glx \
   --disable-dri \
   --with-dri-drivers="" \
   --with-gallium-drivers="" \
   --enable-texture-float \
   --disable-shared-glapi \
   --disable-egl \
   --with-egl-platforms="" \
   --enable-osmesa \
   --enable-gallium-llvm=no \
   --prefix=/usr/local/mesa/10.2.2/classic


to build the Classic OSMesa (not the new Gallium llvmpipe state-tracker)
Here are some build instructions and speed comparisons:
