1309 \`configure' configures GNU C Library (see version.h) to adapt to many kinds of systems.
1310
1311 Usage: $0 [OPTION]... [VAR=VALUE]...
1312
1313 To assign environment variables (e.g., CC, CFLAGS...), specify them as
1314 VAR=VALUE.  See below for descriptions of some of the useful variables.
1315
1316 Defaults for the options are specified in brackets.
1317
1318 Configuration:
1319   -h, --help              display this help and exit
1320       --help=short        display options specific to this package
1321       --help=recursive    display the short help of all the included packages
1322   -V, --version           display version information and exit
1323   -q, --quiet, --silent   do not print \`checking ...' messages
1324       --cache-file=FILE   cache test results in FILE [disabled]
1325   -C, --config-cache      alias for \`--cache-file=config.cache'
1326   -n, --no-create         do not create output files
1327       --srcdir=DIR        find the sources in DIR [configure dir or \`..']
1328
1329 Installation directories:
1330   --prefix=PREFIX         install architecture-independent files in PREFIX
1331                           [$ac_default_prefix]
1332   --exec-prefix=EPREFIX   install architecture-dependent files in EPREFIX
1333                           [PREFIX]
1334
1335 By default, \`make install' will install all the files in
1336 \`$ac_default_prefix/bin', \`$ac_default_prefix/lib' etc.  You can specify
1337 an installation prefix other than \`$ac_default_prefix' using \`--prefix',
1338 for instance \`--prefix=\$HOME'.
1339
1340 For better control, use the options below.

1427   CFLAGS      C compiler flags
1428   LDFLAGS     linker flags, e.g. -L<lib dir> if you have libraries in a
1429               nonstandard directory <lib dir>
1430   LIBS        libraries to pass to the linker, e.g. -l<library>
1431   CPPFLAGS    (Objective) C/C++ preprocessor flags, e.g. -I<include dir> if
1432               you have headers in a nonstandard directory <include dir>
1433   CPP         C preprocessor
1434   CXX         C++ compiler command
1435   CXXFLAGS    C++ compiler flags
1436
1437 Use these variables to override the choices made by `configure' or to help
1438 it to find libraries and programs with nonstandard names/locations.
