[Bug tree-optimization/31152] New: -(x>y) generates wrong code

["anton at mips dot complang dot tuwien dot ac dot at" <gcc-bugzilla at gcc dot gnu dot org>]

The actual gcc version is

gcc version 4.1.2 20061115 (prerelease) (Debian 4.1.1-21)

When compiled and run with this gcc version, using the command line

gcc -O xxx.c && a.out

the attached program outputs -1, whereas the correct output is 0.  If
I use gcc 3.3.6 or leave away the -O flag, the program produces
correct output.
