	No, ISC's standard compiler is *not* ANSI compliant, though the
2.2 compiler includes a POSIX option. Works fine. They do include the LPI
New C compiler which constitutes their ANSI offering, but I never got it
to work right. Since I do so much work with (Uncle) Sam, having a robust
POSIX system is more critical to me than having ANSI.

	While on the subject, binaries compiled under ISC with the POSIX
flag will NOT run under SCO ODT 1.0 or Xenix/386. Is that proper behavior?
Some sort of startup check must be taking place, since all I get on those
non-ISC platforms is something like "POSIX not supported".
