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

1459   CFLAGS      C compiler flags
1460   LDFLAGS     linker flags, e.g. -L<lib dir> if you have libraries in a
1461               nonstandard directory <lib dir>
1462   LIBS        libraries to pass to the linker, e.g. -l<library>
1463   CPPFLAGS    (Objective) C/C++ preprocessor flags, e.g. -I<include dir> if
1464               you have headers in a nonstandard directory <include dir>
1465   CPP         C preprocessor
1466   CXX         C++ compiler command
1467   CXXFLAGS    C++ compiler flags
1468
1469 Use these variables to override the choices made by `configure' or to help
