The real trick is to add -Dalpha to the CFLAGS setting.  The changes
to main.c are only to add some extra includes to support some code
that's suddenly being used.

The #define ASSEMBLER is to prevent most of the code of sys/proc.h
from being included, as it ends up conflicting with some of the
postgresql definitions.  This may or may not work on other versions
of Digital Unix.

Get alpha working.  Yea.  Dwayne Bailey
