1381 \`configure' configures GNU C Library (see version.h) to adapt to many kinds of systems.
1382
1383 Usage: $0 [OPTION]... [VAR=VALUE]...
1384
1385 To assign environment variables (e.g., CC, CFLAGS...), specify them as
1386 VAR=VALUE.  See below for descriptions of some of the useful variables.
1387
1388 Defaults for the options are specified in brackets.
1389
1390 Configuration:
1391   -h, --help              display this help and exit
1392       --help=short        display options specific to this package
1393       --help=recursive    display the short help of all the included packages
1394   -V, --version           display version information and exit
1395   -q, --quiet, --silent   do not print \`checking ...' messages
1396       --cache-file=FILE   cache test results in FILE [disabled]
1397   -C, --config-cache      alias for \`--cache-file=config.cache'
1398   -n, --no-create         do not create output files
1399       --srcdir=DIR        find the sources in DIR [configure dir or \`..']
1400
1401 Installation directories:
1402   --prefix=PREFIX         install architecture-independent files in PREFIX
1403                           [$ac_default_prefix]
1404   --exec-prefix=EPREFIX   install architecture-dependent files in EPREFIX
1405                           [PREFIX]
1406
1407 By default, \`make install' will install all the files in
1408 \`$ac_default_prefix/bin', \`$ac_default_prefix/lib' etc.  You can specify
1409 an installation prefix other than \`$ac_default_prefix' using \`--prefix',

1531   CXX         C++ compiler command
1532   CXXFLAGS    C++ compiler flags
