1336 \`configure' configures GNU C Library (see version.h) to adapt to many kinds of systems.
1337
1338 Usage: $0 [OPTION]... [VAR=VALUE]...
1339
1340 To assign environment variables (e.g., CC, CFLAGS...), specify them as
1341 VAR=VALUE.  See below for descriptions of some of the useful variables.
1342
1343 Defaults for the options are specified in brackets.
1344
1345 Configuration:
1346   -h, --help              display this help and exit
1347       --help=short        display options specific to this package
1348       --help=recursive    display the short help of all the included packages
1349   -V, --version           display version information and exit
1350   -q, --quiet, --silent   do not print \`checking ...' messages
1351       --cache-file=FILE   cache test results in FILE [disabled]
1352   -C, --config-cache      alias for \`--cache-file=config.cache'
1353   -n, --no-create         do not create output files
1354       --srcdir=DIR        find the sources in DIR [configure dir or \`..']
1355
1356 Installation directories:
1357   --prefix=PREFIX         install architecture-independent files in PREFIX
1358                           [$ac_default_prefix]
1359   --exec-prefix=EPREFIX   install architecture-dependent files in EPREFIX
1360                           [PREFIX]
1361
1362 By default, \`make install' will install all the files in
1363 \`$ac_default_prefix/bin', \`$ac_default_prefix/lib' etc.  You can specify
1364 an installation prefix other than \`$ac_default_prefix' using \`--prefix',
1365 for instance \`--prefix=\$HOME'.
1366
1367 For better control, use the options below.
1368
1369 Fine tuning of the installation directories:
1370   --bindir=DIR            user executables [EPREFIX/bin]
1371   --sbindir=DIR           system admin executables [EPREFIX/sbin]
