"Well, POSIX is IEEE standard 1003. I don't think SPEC1170 and XPG are
national/international standards but are something you have to conform to
if you want to call your OS UNIX(tm).
"

This is plain wrong! There are lots of unixes out there that call themselves
UNIX and do not conform exactly to SPEC1170.

Consider for example, also answering your question about ANSI being
a misleadng guide to portability, the return type of sprintf. I don't
have SPEC1170 on hand, but it is a good guess that it is ANSI compliant
here (return type int), but BSD heritage unices (like SunOS) return
char *.

"have to conform to"

and prey who enforces this rule?
