Ultrix/VAX

Hello,

  I'm attempting to compile 6.5.3 on Ultrix/VAX 4.5, using gcc 2.5.7.
Has anyone compiled any version of PostgreSQL under Ultrix/VAX?  The
compile dies at:

make[2]: Entering directory
/usr/users/root/postgresql-6.5.3/src/backend/libpq'
gcc -I../../include -I../../backend   -DNOFIXADE -Wall
-Wmissing-prototypes -I..   -c hba.c
In file included from ../../include/libpq/pqcomm.h:25,

make[1]: Leaving directory
/usr/users/root/postgresql-6.5.3/src/backend'
make: *** [all] Error 2

  I have do not know how to fix this, and even if I managed to resolve
this, I'm sure another problem would pop up, as few things seem to
compile under Ultrix. :)  Has any previous version been ported to this
architecture, is there anything I can do to compile it cleanly?  Thanks
in advance.

Paul
