+    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.  */
