Context diff this time. Remove -m486 compile args for FreeBSD-i386, compile -O2 on i386. Compile with only -O on alpha for codegen safety. Make the port use the TEST_AND_SET for alpha and i386 on FreeBSD. Fix a lot of bogus string formats for outputting pointers (cast to int and %u/%x replaced with no cast and %p), and 'Size'(size_t) are now cast to 'unsigned long' and output with %lu/ Remove an unused variable.
