   Howdy.  I hate to be a bother, but on gnatsweb it said this was fixed in
 gcc3.1.  I just downloaded and installed the gcc3.1 release on my local
 workstation (FreeBSD 4.5), and it's still giving warnings when I compile
 (I was using "-std=c99 -pedantic -O3 -Wall").  So I grepped the source and
 found this in c-decl.c, starting on line 4620:
 
   if (pedantic)
     {
       if (TREE_CONSTANT (size))
         pedwarn ("ISO C89 forbids array `%s' whose size can't be evaluated",
                  name);
       else
         pedwarn ("ISO C89 forbids variable-size array `%s'",
                  name);
     }
 
   Changing "if (pedantic)" to "if (pedantic && !flag_isoc99)" seemed to
 fix the problem.
