Ultrix 4.0: SVID/POSIX compliant?

[Chip Salzenberg]

I'm looking for comments from people who have experience with C
development under Ultrix 4.0.  Specifically, I need to know whether
DEC has done a passable job at complying with ANS C, the SVID and the
POSIX.1 and .2 standards.

We might be porting a large program to Ultrix; its compatibility with
SysV will be a deciding factor in our decision.

We can't be the only ones in this situation; so if anyone has comments
of general interest, I encourage you to post them.
