2772 \`configure' configures libgnu UNUSED-VERSION to adapt to many kinds of systems.
2773
2774 Usage: $0 [OPTION]... [VAR=VALUE]...
2775
2776 To assign environment variables (e.g., CC, CFLAGS...), specify them as
2777 VAR=VALUE.  See below for descriptions of some of the useful variables.
2778
2779 Defaults for the options are specified in brackets.
2780
2781 Configuration:
2782   -h, --help              display this help and exit
2783       --help=short        display options specific to this package
2784       --help=recursive    display the short help of all the included packages
2785   -V, --version           display version information and exit
2786   -q, --quiet, --silent   do not print \`checking ...' messages
2787       --cache-file=FILE   cache test results in FILE [disabled]
2788   -C, --config-cache      alias for \`--cache-file=config.cache'
2789   -n, --no-create         do not create output files
2790       --srcdir=DIR        find the sources in DIR [configure dir or \`..']
2791
2792 Installation directories:
2793   --prefix=PREFIX         install architecture-independent files in PREFIX
2794                           [$ac_default_prefix]
2795   --exec-prefix=EPREFIX   install architecture-dependent files in EPREFIX
2796                           [PREFIX]
2797
2798 By default, \`make install' will install all the files in
2799 \`$ac_default_prefix/bin', \`$ac_default_prefix/lib' etc.  You can specify
2800 an installation prefix other than \`$ac_default_prefix' using \`--prefix',
2801 for instance \`--prefix=\$HOME'.
2802
2803 For better control, use the options below.

2869 Some influential environment variables:
2870   CC          C compiler command
2871   CFLAGS      C compiler flags
2872   LDFLAGS     linker flags, e.g. -L<lib dir> if you have libraries in a
2873               nonstandard directory <lib dir>
2874   LIBS        libraries to pass to the linker, e.g. -l<library>
2875   CPPFLAGS    (Objective) C/C++ preprocessor flags, e.g. -I<include dir> if
2876               you have headers in a nonstandard directory <include dir>
2877   CPP         C preprocessor
2878
2879 Use these variables to override the choices made by `configure' or to help
2880 it to find libraries and programs with nonstandard names/locations.
