1396 \`configure' configures GNU C Library (see version.h) to adapt to many kinds of systems.
1397
1398 Usage: $0 [OPTION]... [VAR=VALUE]...
1399
1400 To assign environment variables (e.g., CC, CFLAGS...), specify them as
1401 VAR=VALUE.  See below for descriptions of some of the useful variables.
1402
1403 Defaults for the options are specified in brackets.
1404
1405 Configuration:
1406   -h, --help              display this help and exit
1407       --help=short        display options specific to this package
1408       --help=recursive    display the short help of all the included packages
1409   -V, --version           display version information and exit
1410   -q, --quiet, --silent   do not print \`checking...' messages
1411       --cache-file=FILE   cache test results in FILE [disabled]
1412   -C, --config-cache      alias for \`--cache-file=config.cache'
1413   -n, --no-create         do not create output files
1414       --srcdir=DIR        find the sources in DIR [configure dir or \`..']
1415
1416 Installation directories:
1417   --prefix=PREFIX         install architecture-independent files in PREFIX
1418                           [$ac_default_prefix]
1419   --exec-prefix=EPREFIX   install architecture-dependent files in EPREFIX
1420                           [PREFIX]
1421
1422 By default, \`make install' will install all the files in
1423 \`$ac_default_prefix/bin', \`$ac_default_prefix/lib' etc.  You can specify
1424 an installation prefix other than \`$ac_default_prefix' using \`--prefix',
1425 for instance \`--prefix=\$HOME'.
1426
1427 For better control, use the options below.

1519 Some influential environment variables:
1520   CC          C compiler command
1521   CFLAGS      C compiler flags
1522   LDFLAGS     linker flags, e.g. -L<lib dir> if you have libraries in a
1523               nonstandard directory <lib dir>
1524   LIBS        libraries to pass to the linker, e.g. -l<library>
1525   CPPFLAGS    C/C++/Objective C preprocessor flags, e.g. -I<include dir> if
1526               you have headers in a nonstandard directory <include dir>
1527   CPP         C preprocessor
1528   CXX         C++ compiler command
1529   CXXFLAGS    C++ compiler flags
1530
1531 Use these variables to override the choices made by `configure' or to help
1532 it to find libraries and programs with nonstandard names/locations.
