[Bug c/36137] New: gcc can't do math

[otte at gnome dot org]

The attached program prints (unsigned) -1 as opposed to 1.
This doesn't happen if intermediate variables are used somewhere in the
process.

I tested gcc 3.4, 4.2.3 (on both x86 and x86-64) with -O0 and -O2, all ended up
with -1.
suncc printed 1.
