1337 \`configure' configures GNU C Library (see version.h) to adapt to many kinds of systems.
1338
1339 Usage: $0 [OPTION]... [VAR=VALUE]...
1340
1341 To assign environment variables (e.g., CC, CFLAGS...), specify them as
1342 VAR=VALUE.  See below for descriptions of some of the useful variables.
1343
1344 Defaults for the options are specified in brackets.
1345
1346 Configuration:
1347   -h, --help              display this help and exit
1348       --help=short        display options specific to this package
1349       --help=recursive    display the short help of all the included packages
1350   -V, --version           display version information and exit
1351   -q, --quiet, --silent   do not print \`checking ...' messages
1352       --cache-file=FILE   cache test results in FILE [disabled]
1353   -C, --config-cache      alias for \`--cache-file=config.cache'
1354   -n, --no-create         do not create output files
1355       --srcdir=DIR        find the sources in DIR [configure dir or \`..']
1356
1357 Installation directories:
1358   --prefix=PREFIX         install architecture-independent files in PREFIX
1359                           [$ac_default_prefix]
1360   --exec-prefix=EPREFIX   install architecture-dependent files in EPREFIX
1361                           [PREFIX]
1362
1363 By default, \`make install' will install all the files in
1364 \`$ac_default_prefix/bin', \`$ac_default_prefix/lib' etc.  You can specify
1365 an installation prefix other than \`$ac_default_prefix' using \`--prefix',
1366 for instance \`--prefix=\$HOME'.
1367
1368 For better control, use the options below.

1370 Fine tuning of the installation directories:
1371   --bindir=DIR            user executables [EPREFIX/bin]

1467   CFLAGS      C compiler flags
1468   LDFLAGS     linker flags, e.g. -L<lib dir> if you have libraries in a
1469               nonstandard directory <lib dir>
1470   LIBS        libraries to pass to the linker, e.g. -l<library>
1471   CPPFLAGS    (Objective) C/C++ preprocessor flags, e.g. -I<include dir> if
1472               you have headers in a nonstandard directory <include dir>
1473   CPP         C preprocessor
1474   CXX         C++ compiler command
1475   CXXFLAGS    C++ compiler flags
1476
1477 Use these variables to override the choices made by `configure' or to help
1478 it to find libraries and programs with nonstandard names/locations.
