# MAKEFILE for linux GCC

# NOTE: This should later be replaced by autoconf/automake scripts, but for
# the time being this is actually pretty clean. The only ugly part is
# handling CFLAGS so that the x86 specific optimizations don't break
# a build. This is easy to remedy though, for those that have problems.
