compiled for any SPARC CPU (UltraSPARC performance is *not* affected),
can be compiled for 64-bit ABI and is position-independent.

It was not accepted because code is not PIC, too UltraSPARC-specific when
it doesn't have to and 32-bit only. I'm committing the original version
mostly for reference purposes. 64, PIC, blended CPU tune-up follows shortly.
