hi, trying to compile postgres 8.3.11

hi,
i tried to compile postgres 8.3.11 on SCO OpenServer 5.0.7, but ...
when   the xlog.o is being compiled  i have the next error:

/usr/tmp/ccihgiYL.s: 1113: syntax error at name f
/usr/tmp/ccihgiYL.s: 1113: syntax error at integer constant: 1

i dont have copy of that  assembly file  because  was deleted...

What can i do  to solve this? by the way  i've compiled postgres 8.3.1
and i don't have problem.
