1360 \`configure' configures GNU C Library (see version.h) to adapt to many kinds of systems.
1361
1362 Usage: $0 [OPTION]... [VAR=VALUE]...
1363
1364 To assign environment variables (e.g., CC, CFLAGS...), specify them as
1365 VAR=VALUE.  See below for descriptions of some of the useful variables.
1366
1367 Defaults for the options are specified in brackets.
1368
1369 Configuration:
1370   -h, --help              display this help and exit
1371       --help=short        display options specific to this package
1372       --help=recursive    display the short help of all the included packages
1373   -V, --version           display version information and exit
1374   -q, --quiet, --silent   do not print \`checking ...' messages
1375       --cache-file=FILE   cache test results in FILE [disabled]
1376   -C, --config-cache      alias for \`--cache-file=config.cache'
1377   -n, --no-create         do not create output files
1378       --srcdir=DIR        find the sources in DIR [configure dir or \`..']
1379
1380 Installation directories:
1381   --prefix=PREFIX         install architecture-independent files in PREFIX
1382                           [$ac_default_prefix]
1383   --exec-prefix=EPREFIX   install architecture-dependent files in EPREFIX
1384                           [PREFIX]
1385
1386 By default, \`make install' will install all the files in
1387 \`$ac_default_prefix/bin', \`$ac_default_prefix/lib' etc.  You can specify
1388 an installation prefix other than \`$ac_default_prefix' using \`--prefix',
1389 for instance \`--prefix=\$HOME'.
