1341 \`configure' configures GNU C Library (see version.h) to adapt to many kinds of systems.
1342
1343 Usage: $0 [OPTION]... [VAR=VALUE]...
1344
1345 To assign environment variables (e.g., CC, CFLAGS...), specify them as
1346 VAR=VALUE.  See below for descriptions of some of the useful variables.
1347
1348 Defaults for the options are specified in brackets.
1349
1350 Configuration:
1351   -h, --help              display this help and exit
1352       --help=short        display options specific to this package
1353       --help=recursive    display the short help of all the included packages
1354   -V, --version           display version information and exit
1355   -q, --quiet, --silent   do not print \`checking ...' messages
1356       --cache-file=FILE   cache test results in FILE [disabled]
1357   -C, --config-cache      alias for \`--cache-file=config.cache'
1358   -n, --no-create         do not create output files
1359       --srcdir=DIR        find the sources in DIR [configure dir or \`..']
1360
1361 Installation directories:
1362   --prefix=PREFIX         install architecture-independent files in PREFIX
1363                           [$ac_default_prefix]
1364   --exec-prefix=EPREFIX   install architecture-dependent files in EPREFIX
1365                           [PREFIX]
1366
1367 By default, \`make install' will install all the files in
1368 \`$ac_default_prefix/bin', \`$ac_default_prefix/lib' etc.  You can specify
1369 an installation prefix other than \`$ac_default_prefix' using \`--prefix',
1370 for instance \`--prefix=\$HOME'.
1371
1372 For better control, use the options below.
1373
1374 Fine tuning of the installation directories:
1375   --bindir=DIR            user executables [EPREFIX/bin]
1376   --sbindir=DIR           system admin executables [EPREFIX/sbin]
1377   --libexecdir=DIR        program executables [EPREFIX/libexec]
1378   --sysconfdir=DIR        read-only single-machine data [PREFIX/etc]
1379   --sharedstatedir=DIR    modifiable architecture-independent data [PREFIX/com]

1381   --libdir=DIR            object code libraries [EPREFIX/lib]
