ANSI-C: Both the MIPS compiler and the vax compilers have not been enhanced to
the point that they could be called ANSI-C compliant. GNU-CC is still
your best option for ANSI.
SVID: Ultrix 4.0 is compatible with select pieces of SVID issue 2. I believe
that the sales blurbs explain which of the select pieces DEC chose.
POSIX: In 4.0, we have made extensive use of PCTS (Posix compliancy test suite)
which tests the .1 capabilities. If you find items in 4.0 which are not
.1 compliant, report a QAR, because this should not be the case. .2 on
the other hand I don't believe has been fully addressed (yet).
XPG3: As announced earlier this year, Ultrix 4.0 has been validated XPG3
compliant (the base part). DEC did submit a few waivers, but these
are being fixed rapidly and probably won't be noticed by the large
majority of the users.
