2444 \`configure' configures libgnu UNUSED-VERSION to adapt to many kinds of systems.
2445
2446 Usage: $0 [OPTION]... [VAR=VALUE]...
2447
2448 To assign environment variables (e.g., CC, CFLAGS...), specify them as
2449 VAR=VALUE.  See below for descriptions of some of the useful variables.
2450
2451 Defaults for the options are specified in brackets.
2452
2453 Configuration:
2454   -h, --help              display this help and exit
2455       --help=short        display options specific to this package
2456       --help=recursive    display the short help of all the included packages
2457   -V, --version           display version information and exit
2458   -q, --quiet, --silent   do not print \`checking ...' messages
2459       --cache-file=FILE   cache test results in FILE [disabled]
2460   -C, --config-cache      alias for \`--cache-file=config.cache'
2461   -n, --no-create         do not create output files
2462       --srcdir=DIR        find the sources in DIR [configure dir or \`..']
2463
2464 Installation directories:
2465   --prefix=PREFIX         install architecture-independent files in PREFIX
2466                           [$ac_default_prefix]
2467   --exec-prefix=EPREFIX   install architecture-dependent files in EPREFIX
2468                           [PREFIX]
2469
2470 By default, \`make install' will install all the files in
2471 \`$ac_default_prefix/bin', \`$ac_default_prefix/lib' etc.  You can specify
2472 an installation prefix other than \`$ac_default_prefix' using \`--prefix',
2473 for instance \`--prefix=\$HOME'.
2474
2475 For better control, use the options below.

2540 Some influential environment variables:
2541   CC          C compiler command
2542   CFLAGS      C compiler flags
2543   LDFLAGS     linker flags, e.g. -L<lib dir> if you have libraries in a
2544               nonstandard directory <lib dir>
2545   LIBS        libraries to pass to the linker, e.g. -l<library>
2546   CPPFLAGS    (Objective) C/C++ preprocessor flags, e.g. -I<include dir> if
2547               you have headers in a nonstandard directory <include dir>
2548   CPP         C preprocessor
2549
2550 Use these variables to override the choices made by `configure' or to help
2551 it to find libraries and programs with nonstandard names/locations.
