I checked in the following patch, which should fix those problems:

2002-11-14  Paul Eggert  <address@hidden>

        * tests/headers.at (AT_TEST_CPP_GUARD_H): Don't assume that
        "$CC -E foo.h" is allowed, as this doesn't work with the Portland
        Group compiler.  Instead, use "$CC -E bar.c".  Include the .h
        file twice in the grammar, as an extra check.
