What I meant is that, in the hypothetical situation where we
const-qualified things accidentally, if we were using GCC 2.95/stabs (a
combination which "we, the testsuite" know can not say "const"!)
printing out const would be quite surprising.

This is completely unimportant, of course.

It's not there.  I can add it trivially, if you want.  The major
version is there already; it's [ $gcc_compiled > 2 ].  We could just
set gcc_compiler_minor if necessary.  They're __GNUC__ and
__GNUC_MINOR__.

Thanks.
