I'm sorry; I'll add 2009 today.  I don't know of a rule about adding
years in which no changes were made, but I can certainly do that if
people think it's the standard practice.

I didn't notice them because the simulator I was using didn't have that
enabled, but I agree that it makes sense.  Is it pre-approved to make
the corresponding changes to the corresponding wchar_t tests?

Y'all should use templates to avoid this code duplication in the tests.
:-p :-)

More generally, I actually think "simulator" is the wrong predicate.  It
should be "slow target" (which doesn't exist as a predicate at present);
"simulator" is just a special case of that.  A little microcontroller
might well have the same problem.  We could honor a setting in the
DejaGNU board file, falling back to "simulator" if the board didn't
explicitly set the flag.

Thanks,
