o Add register prefixes for the benefit of gas.new
o Wrap global symbols in the m68k/asm.h macros
o Fix `#' comments so the source can be run through the C pre-processor
movs.
XXX As our CPP seems to hate the 060SP, I couldn't use assym.h for the
PCB_ONFAULT definition, but had to hardwire 64 in the code. This needs
to be fixed ASAP, and will be done in the upcoming reorganization of
the 060sp Makefiles.
_buserr point to the 68020/030 buserr code _only_. This has broken access
error handling in the 060 support code.
This is repaired by jumping to _buserr60 from the 060SP, and by providing
a _buserr60 label identical to the _buserr in the unchanged m68k ports
using the 68060.
