Subject: [PATCH] intprops-test: fix compilation warning on 32 bit

Compiling on 32 bit gave the following error:
test-intprops.c:325:34: error: integer overflow in expression
             || result == INT_MAX * (long int) INT_MAX);

* tests/test-intprops.c [__GNUC__]: Ignore -Werror=overflow.
* lib/intprops.h: Fix an incorrect example in a comment.
