The point I was making here was that NO ANSI Standard yet exists, hence
no ANSI-conformant compiler can exist.  The Standard is still in the
Proposed state, though very close (finally) to being approved and made
an official ANSI Standard.... whether the ISO will approve it is another
matter but I think ANSI is all most of the North American implementors
really care about anyhow...

There are definitely some validation suites out there... I've had experience
with the Plum Hall suite.  The suites are quite expensive to license and
must constantly be updated because the Drafts have been changing (and bugs
keep being found in the suites).  I haven't heard that ANSI will be 
adopting any suite for use in certification tests, but I know the British
are looking at using one suite for official validation.

As I see it the real headache in the next few years will be getting people
to convert to ANSI-style compilers.  I cringe whenever I'm forced to use
`cc'... I miss the prototypes and the new-style declarations.  I think it's
a good idea to encourage people to use any conversion tools available to
convert old C into new C... as long as the new C code doesn't break, of
course.
