sorry, doesn't compile under gcc-3.4. after replacing text labels with
numerical, and removing const qualifiers from the precomputed fixed
point constants (they were optimized out, so linker blew up later due to
their usage in assembler), -vf spp crashes with a segfault (I can
provide a more detailed report if needed).
