Added Makefile for building syborg-graphicswrapper using GCC At present the build fails due to the following missing headers: KhronosAPIWrapper.h VirtualVideoInterfaceConstants.h platformthreading.h protocol_MGraphicsVHWCallback.h

# f.close() is not thread-safe: calling it at the same time as another
# operation (or another close) on the same file, but done from another
# thread, causes crashes.  The issue is more complicated than it seems,
# witness the discussions in:
#
# http://bugs.python.org/issue595601
# http://bugs.python.org/issue815646
