I've committed this test to the mainline's testsuite. It will fail with
the mainline compiler on ppc-linux native with -O2.
The test (and the larger source from which it was derived) compiles just
fine with 2.95.3, so this represents a regression compared to our older
compilers.
I'm not currently debugging this problem.
* g77.f-torture/compile/20020307-1.f: New test.
