/* Catch a bug in IBM AIX xlc compiler version 6.0.0.0

This test is not quite right, since xlc is allowed to
70
reject this program, as the initializer for xlcbug is
71
not one of the forms that C requires support for.
72
However, doing the test right would require a run-time
73
test, and that would make cross-compilation harder.
74
Let us hope that IBM fixes the xlc bug, and also adds
75
support for this kind of constant expression. In the
76
meantime, this test will reject xlc, which is OK, since
77
our stdbool.h substitute should suffice. We also test
78
this with GCC, where it should work, to detect more
79
quickly whether someone messes up the test in the
81
