Subject: test-intprops: disable -Wtype-limits diagnostics

test-intprops: disable -Wtype-limits diagnostics

* tests/test-intprops.c: Use a pragma to ignore -Wtype-limits
diagnostics.  Otherwise, the integer overflow macros generate many
diagnostics.  Reported by Jim Meyering in
<http://lists.gnu.org/archive/html/bug-gnulib/2011-05/msg00528.html>.
