I tried to reply via mail but someone claims not to know about your site.
Maybe this header will be of some help to you:

  Anyway, the reason I am repling is that I have already done what you are
intending to do.  Some minor changes needed to be made to gcc and
gas - these included stuff to tell gcc that ints were 16 bits (there are
problems with passing arguments for bios calls otherwise, also much faster)
and some changes to get gas to dump .o files that are usable on the sun
(so I could adb them there...).  Other stuff that was needed was a program to
convert unix a.out executables to gem format, long multiplication/
division/modulo routines for gcc, and of course libc (which is still under
construction).  If you want some/all of the stuff I have done just send a
note (I hacked 4.3bsd (vax) ld/strip/size/nm/ranlib so I can't just send
them to you - maybe diffs if you have a source licience?) The only thing
that is really missing is floating point routines - any sugestions as to
PD versions (in C or assembler) for these would be helpful.
