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.
