1316 \`configure' configures GNU C Library (see version.h) to adapt to many kinds of systems.
1317
1318 Usage: $0 [OPTION]... [VAR=VALUE]...
1319
1320 To assign environment variables (e.g., CC, CFLAGS...), specify them as
1321 VAR=VALUE.  See below for descriptions of some of the useful variables.
1322
1323 Defaults for the options are specified in brackets.
1324
1325 Configuration:
1326   -h, --help              display this help and exit
1327       --help=short        display options specific to this package
1328       --help=recursive    display the short help of all the included packages
1329   -V, --version           display version information and exit
1330   -q, --quiet, --silent   do not print \`checking ...' messages
1331       --cache-file=FILE   cache test results in FILE [disabled]
1332   -C, --config-cache      alias for \`--cache-file=config.cache'
1333   -n, --no-create         do not create output files
1334       --srcdir=DIR        find the sources in DIR [configure dir or \`..']
1335
1336 Installation directories:
1337   --prefix=PREFIX         install architecture-independent files in PREFIX
1338                           [$ac_default_prefix]
1339   --exec-prefix=EPREFIX   install architecture-dependent files in EPREFIX
1340                           [PREFIX]
1341
1342 By default, \`make install' will install all the files in
1343 \`$ac_default_prefix/bin', \`$ac_default_prefix/lib' etc.  You can specify
1344 an installation prefix other than \`$ac_default_prefix' using \`--prefix',
1345 for instance \`--prefix=\$HOME'.
1346
1347 For better control, use the options below.

1445   CFLAGS      C compiler flags
1446   LDFLAGS     linker flags, e.g. -L<lib dir> if you have libraries in a
1447               nonstandard directory <lib dir>
1448   LIBS        libraries to pass to the linker, e.g. -l<library>
1449   CPPFLAGS    (Objective) C/C++ preprocessor flags, e.g. -I<include dir> if
1450               you have headers in a nonstandard directory <include dir>
1451   CPP         C preprocessor
1452   CXX         C++ compiler command
1453   CXXFLAGS    C++ compiler flags
1454
1455 Use these variables to override the choices made by `configure' or to help
1456 it to find libraries and programs with nonstandard names/locations.
