/* 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. */
