1383 \`configure' configures GNU C Library (see version.h) to adapt to many kinds of systems.
1384
1385 Usage: $0 [OPTION]... [VAR=VALUE]...
1386
1387 To assign environment variables (e.g., CC, CFLAGS...), specify them as
1388 VAR=VALUE.  See below for descriptions of some of the useful variables.
1389
1390 Defaults for the options are specified in brackets.
1391
1392 Configuration:
1393   -h, --help              display this help and exit
1394       --help=short        display options specific to this package
1395       --help=recursive    display the short help of all the included packages
1396   -V, --version           display version information and exit
1397   -q, --quiet, --silent   do not print \`checking ...' messages
1398       --cache-file=FILE   cache test results in FILE [disabled]
1399   -C, --config-cache      alias for \`--cache-file=config.cache'
1400   -n, --no-create         do not create output files
1401       --srcdir=DIR        find the sources in DIR [configure dir or \`..']
1402
1403 Installation directories:
1404   --prefix=PREFIX         install architecture-independent files in PREFIX
1405                           [$ac_default_prefix]
1406   --exec-prefix=EPREFIX   install architecture-dependent files in EPREFIX
1407                           [PREFIX]
1408
1409 By default, \`make install' will install all the files in
1410 \`$ac_default_prefix/bin', \`$ac_default_prefix/lib' etc.  You can specify
1411 an installation prefix other than \`$ac_default_prefix' using \`--prefix',
1412 for instance \`--prefix=\$HOME'.
1413
1414 For better control, use the options below.
