ANSI C testing ??

[rja]

I'm interested in knowing how far the DEC VAX/VMS C Compiler (for VMS 5.3) 
is from being ANSI C.  DEC doesn't claim that it is an ANSI compiler,
but the compiler does have a number of "modern" features.  DEC declines
to address the question of "how far out" they are from ANSI C and won't
address the question of "when will VMS C be ANSI compliant" either.

Similarly, Intel iC86 claims to be ANSI (except for some documented
non-standard kludges like "far" and "near" to compensate for their hardware)
but I'm unconvinced since so many vendors are claiming full ANSI C when
in fact they are only maybe 90% ANSI C.  Has anyone run into any ANSI C
deficiencies in iC86 ???

We'd like to run some kind of test suite across the compilers we're
considering using  (the above and some others).  Since we aren't a
compiler vendor it is hard to justify spending a lot of money on 
developing or purchasing such a thing.  Still, we'd like to have
something to test with if it is freely distributable or affordable.

If you have any information on any of this, please drop me mail 
and I'll post a short summary of what I hear.

Thanks,

  Ran
