+              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.  */
