Thanks.  For the record, I'm holding off this patch in favour of
Janis's more comprehensive one:

    http://gcc.gnu.org/ml/gcc-patches/2004-11/msg00172.html

If that patch is accepted, would it be OK to use:

    { dg-require-effective-target ilp32 }

instead of dg-require-int-sized-pointers?

If not, an alternative would be to add a new dg-require-effective-target
keyword that tests the same thing as dg-require-int-sized-pointers
(ref: http://gcc.gnu.org/ml/gcc-patches/2004-11/msg00215.html).

True, but since lots of code does seem to cast pointers to or from int,
I guess it's nice to have something for it in the testsuite...
