 /* Catch a bug in IBM AIX xlc compiler version 6.0.0.0
    reported by James Lemley on 2005-10-05; see
    http://lists.gnu.org/archive/html/bug-coreutils/2005-10/msg00086.html
    This test is not quite right, since xlc is allowed to
    reject this program, as the initializer for xlcbug is
    not one of the forms that C requires support for.
    However, doing the test right would require a run-time
    test, and that would make cross-compilation harder.
    Let us hope that IBM fixes the xlc bug, and also adds
    support for this kind of constant expression.  In the
    meantime, this test will reject xlc, which is OK, since
    our stdbool.h substitute should suffice.  We also test
    this with GCC, where it should work, to detect more
    quickly whether someone messes up the test in the
    future.  */
