1331 \`configure' configures GNU C Library (see version.h) to adapt to many kinds of systems.
1332
1333 Usage: $0 [OPTION]... [VAR=VALUE]...
1334
1335 To assign environment variables (e.g., CC, CFLAGS...), specify them as
1336 VAR=VALUE.  See below for descriptions of some of the useful variables.
1337
1338 Defaults for the options are specified in brackets.
1339
1340 Configuration:
1341   -h, --help              display this help and exit
1342       --help=short        display options specific to this package
1343       --help=recursive    display the short help of all the included packages
1344   -V, --version           display version information and exit
1345   -q, --quiet, --silent   do not print \`checking ...' messages
1346       --cache-file=FILE   cache test results in FILE [disabled]
1347   -C, --config-cache      alias for \`--cache-file=config.cache'
1348   -n, --no-create         do not create output files
1349       --srcdir=DIR        find the sources in DIR [configure dir or \`..']
1350
1351 Installation directories:
1352   --prefix=PREFIX         install architecture-independent files in PREFIX
1353                           [$ac_default_prefix]
1354   --exec-prefix=EPREFIX   install architecture-dependent files in EPREFIX
1355                           [PREFIX]
1356
1357 By default, \`make install' will install all the files in
1358 \`$ac_default_prefix/bin', \`$ac_default_prefix/lib' etc.  You can specify
1359 an installation prefix other than \`$ac_default_prefix' using \`--prefix',
1360 for instance \`--prefix=\$HOME'.
1361
1362 For better control, use the options below.

1365   --bindir=DIR            user executables [EPREFIX/bin]
