This patch makes it possible to build classic osmesa/swrast on windows
again. Although there is a gallium version of osmesa now, the swrast version
still has more features lacking in llvmpipe, e.g. anisotropic filtering.
This reverts commit 69db422218b0264b5b8eef45bd003a2544e9cbd6 and
c07df0f2014636b601cdbaff63214296599b1ad5 and adds "compiler" to
the LIBS in SConscript.
