I'm afraid the testcase will fail on int16 targets, so perhaps
you should guard the body of main other than return 0; with
#if __INT_MAX__ >= 2147483647ULL
or
#if __SIZEOF_INT__ >= 4
or similar (or require int32plus target, but gcc.c-torture/execute/
is not a good place for that and *.x files are terribly ugly, so
better would be to move the test to gcc.dg/torture/ in that case).
