1348 \`configure' configures GNU C Library (see version.h) to adapt to many kinds of systems.
1349
1350 Usage: $0 [OPTION]... [VAR=VALUE]...
1351
1352 To assign environment variables (e.g., CC, CFLAGS...), specify them as
1353 VAR=VALUE.  See below for descriptions of some of the useful variables.
1354
1355 Defaults for the options are specified in brackets.
1356
1357 Configuration:
1358   -h, --help              display this help and exit
1359       --help=short        display options specific to this package
1360       --help=recursive    display the short help of all the included packages
1361   -V, --version           display version information and exit
1362   -q, --quiet, --silent   do not print \`checking ...' messages
1363       --cache-file=FILE   cache test results in FILE [disabled]
1364   -C, --config-cache      alias for \`--cache-file=config.cache'
1365   -n, --no-create         do not create output files
1366       --srcdir=DIR        find the sources in DIR [configure dir or \`..']
1367
1368 Installation directories:
1369   --prefix=PREFIX         install architecture-independent files in PREFIX
1370                           [$ac_default_prefix]
1371   --exec-prefix=EPREFIX   install architecture-dependent files in EPREFIX
1372                           [PREFIX]
1373
1374 By default, \`make install' will install all the files in
1375 \`$ac_default_prefix/bin', \`$ac_default_prefix/lib' etc.  You can specify
1376 an installation prefix other than \`$ac_default_prefix' using \`--prefix',
1377 for instance \`--prefix=\$HOME'.
1378
1379 For better control, use the options below.
1380
1381 Fine tuning of the installation directories:
1382   --bindir=DIR            user executables [EPREFIX/bin]
1383   --sbindir=DIR           system admin executables [EPREFIX/sbin]
1384   --libexecdir=DIR        program executables [EPREFIX/libexec]
1385   --sysconfdir=DIR        read-only single-machine data [PREFIX/etc]
1386   --sharedstatedir=DIR    modifiable architecture-independent data [PREFIX/com]
