partially reduced test case for -O2 -fplugin-arg-dragonegg-enable-gcc-optzns

The -O2 -fplugin-arg-dragonegg-enable-gcc-optzns fails to compile the
fatigue.f90 benchmark on x86_64-apple-darwin10. The reduced testcase of just
the main program from the fatigue.f90 benchmark also exhibits this problem...
