1210	Usage: $0 [OPTION]... [VAR=VALUE]...
1211
1212	To assign environment variables (e.g., CC, CFLAGS...), specify them as
1213	VAR=VALUE. See below for descriptions of some of the useful variables.
1214
1215	Defaults for the options are specified in brackets.
1216
1217	Configuration:
1218	-h, --help display this help and exit
1219	--help=short display options specific to this package
1220	--help=recursive display the short help of all the included packages
1221	-V, --version display version information and exit
1222	-q, --quiet, --silent do not print \`checking...' messages
1223	--cache-file=FILE cache test results in FILE [disabled]
1224	-C, --config-cache alias for \`--cache-file=config.cache'
1225	-n, --no-create do not create output files
1226	--srcdir=DIR find the sources in DIR [configure dir or \`..']
1227
1228	Installation directories:
1229	--prefix=PREFIX install architecture-independent files in PREFIX
1230	[$ac_default_prefix]
1231	--exec-prefix=EPREFIX install architecture-dependent files in EPREFIX
1232	[PREFIX]
1233
1234	By default, \`make install' will install all the files in
1235	\`$ac_default_prefix/bin', \`$ac_default_prefix/lib' etc. You can specify
1236	an installation prefix other than \`$ac_default_prefix' using \`--prefix',
1237	for instance \`--prefix=\$HOME'.
1238

4283	Let us hope that IBM fixes the xlc bug, and also adds
4284	support for this kind of constant expression. In the
4285	meantime, this test will reject xlc, which is OK, since
4286	our stdbool.h substitute should suffice. We also test
