1333 \`configure' configures GNU C Library (see version.h) to adapt to many kinds of systems.
1334
1335 Usage: $0 [OPTION]... [VAR=VALUE]...
1336
1337 To assign environment variables (e.g., CC, CFLAGS...), specify them as
1338 VAR=VALUE.  See below for descriptions of some of the useful variables.
1339
1340 Defaults for the options are specified in brackets.
1341
1342 Configuration:
1343   -h, --help              display this help and exit
1344       --help=short        display options specific to this package
1345       --help=recursive    display the short help of all the included packages
1346   -V, --version           display version information and exit
1347   -q, --quiet, --silent   do not print \`checking ...' messages
1348       --cache-file=FILE   cache test results in FILE [disabled]
1349   -C, --config-cache      alias for \`--cache-file=config.cache'
1350   -n, --no-create         do not create output files
1351       --srcdir=DIR        find the sources in DIR [configure dir or \`..']
1352
1353 Installation directories:
1354   --prefix=PREFIX         install architecture-independent files in PREFIX
1355                           [$ac_default_prefix]
1356   --exec-prefix=EPREFIX   install architecture-dependent files in EPREFIX
1357                           [PREFIX]
1358
1359 By default, \`make install' will install all the files in
1360 \`$ac_default_prefix/bin', \`$ac_default_prefix/lib' etc.  You can specify
1361 an installation prefix other than \`$ac_default_prefix' using \`--prefix',
1362 for instance \`--prefix=\$HOME'.
1363
1364 For better control, use the options below.
1365
1366 Fine tuning of the installation directories:
1367   --bindir=DIR            user executables [EPREFIX/bin]
1368   --sbindir=DIR           system admin executables [EPREFIX/sbin]
