Thanks.  At least some of those errors (on Linux) are "sigset_t", which
also appear on Solaris.

Let's just backtrack a moment.

Is the following correct?  The intented purpose ("service delivery", "end
of the day" sort of concept) of this "--enable-ansi" was to catch things
such as "//" comments that cause problems to various compilers and that
can be reasonably avoided.  Correct?  We weren't actually wishing to
enforce ANSI standard C which might cause trouble, as seems to be the
case, with certain ANSI v. POSIX v. ... environmental things (e.g.
"sigset_t").  Correct?

If so, is the "-ansi" option (gcc) the most appropriate vehicle for this?
Or are its side-effects (e.g. "sigset_t" etc.) highly undesirable for us?

Might there be a better way to trap these "//"-like programming errors?

For instance a quick look through "gcc -v --help" (on my 2.95.2 compiler)
shows "-pedantic" and "-std=<standard>" (e.g. "c89", "c9x", etc.). Might
one of these be a better vehicle than "-ansi" for achieving that intended
purpose?
