1349 \`configure' configures GNU C Library (see version.h) to adapt to many kinds of systems.
1350
1351 Usage: $0 [OPTION]... [VAR=VALUE]...
1352
1353 To assign environment variables (e.g., CC, CFLAGS...), specify them as
1354 VAR=VALUE.  See below for descriptions of some of the useful variables.
1355
1356 Defaults for the options are specified in brackets.
1357
1358 Configuration:
1359   -h, --help              display this help and exit
1360       --help=short        display options specific to this package
1361       --help=recursive    display the short help of all the included packages
1362   -V, --version           display version information and exit
1363   -q, --quiet, --silent   do not print \`checking ...' messages
1364       --cache-file=FILE   cache test results in FILE [disabled]
1365   -C, --config-cache      alias for \`--cache-file=config.cache'
1366   -n, --no-create         do not create output files
1367       --srcdir=DIR        find the sources in DIR [configure dir or \`..']
1368
1369 Installation directories:
1370   --prefix=PREFIX         install architecture-independent files in PREFIX
1371                           [$ac_default_prefix]
1372   --exec-prefix=EPREFIX   install architecture-dependent files in EPREFIX
1373                           [PREFIX]
1374
1375 By default, \`make install' will install all the files in
1376 \`$ac_default_prefix/bin', \`$ac_default_prefix/lib' etc.  You can specify
1377 an installation prefix other than \`$ac_default_prefix' using \`--prefix',
1378 for instance \`--prefix=\$HOME'.
1379
1380 For better control, use the options below.
1381
1382 Fine tuning of the installation directories:
1383   --bindir=DIR            user executables [EPREFIX/bin]
1384   --sbindir=DIR           system admin executables [EPREFIX/sbin]
1385   --libexecdir=DIR        program executables [EPREFIX/libexec]
1386   --sysconfdir=DIR        read-only single-machine data [PREFIX/etc]
1387   --sharedstatedir=DIR    modifiable architecture-independent data [PREFIX/com]
