1344 \`configure' configures GNU C Library (see version.h) to adapt to many kinds of systems.
1345
1346 Usage: $0 [OPTION]... [VAR=VALUE]...
1347
1348 To assign environment variables (e.g., CC, CFLAGS...), specify them as
1349 VAR=VALUE.  See below for descriptions of some of the useful variables.
1350
1351 Defaults for the options are specified in brackets.
1352
1353 Configuration:
1354   -h, --help              display this help and exit
1355       --help=short        display options specific to this package
1356       --help=recursive    display the short help of all the included packages
1357   -V, --version           display version information and exit
1358   -q, --quiet, --silent   do not print \`checking ...' messages
1359       --cache-file=FILE   cache test results in FILE [disabled]
1360   -C, --config-cache      alias for \`--cache-file=config.cache'
1361   -n, --no-create         do not create output files
1362       --srcdir=DIR        find the sources in DIR [configure dir or \`..']
1363
1364 Installation directories:
1365   --prefix=PREFIX         install architecture-independent files in PREFIX
1366                           [$ac_default_prefix]
1367   --exec-prefix=EPREFIX   install architecture-dependent files in EPREFIX
1368                           [PREFIX]
1369
1370 By default, \`make install' will install all the files in
1371 \`$ac_default_prefix/bin', \`$ac_default_prefix/lib' etc.  You can specify
1372 an installation prefix other than \`$ac_default_prefix' using \`--prefix',
1373 for instance \`--prefix=\$HOME'.
1374
1375 For better control, use the options below.
1376
1377 Fine tuning of the installation directories:
1378   --bindir=DIR            user executables [EPREFIX/bin]
1379   --sbindir=DIR           system admin executables [EPREFIX/sbin]
1380   --libexecdir=DIR        program executables [EPREFIX/libexec]
1381   --sysconfdir=DIR        read-only single-machine data [PREFIX/etc]
1382   --sharedstatedir=DIR    modifiable architecture-independent data [PREFIX/com]
1383   --localstatedir=DIR     modifiable single-machine data [PREFIX/var]

1461   CFLAGS      C compiler flags
1462   LDFLAGS     linker flags, e.g. -L<lib dir> if you have libraries in a
1463               nonstandard directory <lib dir>
1464   LIBS        libraries to pass to the linker, e.g. -l<library>
1465   CPPFLAGS    (Objective) C/C++ preprocessor flags, e.g. -I<include dir> if
1466               you have headers in a nonstandard directory <include dir>
1467   CPP         C preprocessor
1468   CXX         C++ compiler command
1469   CXXFLAGS    C++ compiler flags
1470
1471 Use these variables to override the choices made by `configure' or to help
