2566 \`configure' configures libgnu UNUSED-VERSION to adapt to many kinds of systems.
2567
2568 Usage: $0 [OPTION]... [VAR=VALUE]...
2569
2570 To assign environment variables (e.g., CC, CFLAGS...), specify them as
2571 VAR=VALUE. See below for descriptions of some of the useful variables.
2572
2573 Defaults for the options are specified in brackets.
2574
2575 Configuration:
2576 -h, --help display this help and exit
2577 --help=short display options specific to this package
2578 --help=recursive display the short help of all the included packages
2579 -V, --version display version information and exit
2580 -q, --quiet, --silent do not print \`checking ...' messages
2581 --cache-file=FILE cache test results in FILE [disabled]
2582 -C, --config-cache alias for \`--cache-file=config.cache'
2583 -n, --no-create do not create output files
2584 --srcdir=DIR find the sources in DIR [configure dir or \`..']
2585
2586 Installation directories:
2587 --prefix=PREFIX install architecture-independent files in PREFIX
2588 [$ac_default_prefix]
2589 --exec-prefix=EPREFIX install architecture-dependent files in EPREFIX
2590 [PREFIX]
2591
2592 By default, \`make install' will install all the files in
2593 \`$ac_default_prefix/bin', \`$ac_default_prefix/lib' etc. You can specify
2594 an installation prefix other than \`$ac_default_prefix' using \`--prefix',
2595 for instance \`--prefix=\$HOME'.
2596
2597 For better control, use the options below.

2644 --enable-FEATURE[=ARG] include FEATURE [ARG=yes]
2645 --enable-maintainer-mode
2646 enable make rules and dependencies not useful (and
2647 sometimes confusing) to the casual installer
2648 --enable-plugins Enable support for plugins
2649 --disable-largefile omit support for large files
2650 --enable-threads={isoc|posix|isoc+posix|windows}

2662 Some influential environment variables:
2663 CC C compiler command
2664 CFLAGS C compiler flags
2665 LDFLAGS linker flags, e.g. -L<lib dir> if you have libraries in a
2666 nonstandard directory <lib dir>
2667 LIBS libraries to pass to the linker, e.g. -l<library>
2668 CPPFLAGS (Objective) C/C++ preprocessor flags, e.g. -I<include dir> if
2669 you have headers in a nonstandard directory <include dir>
2670 CPP C preprocessor
2671
2672 Use these variables to override the choices made by `configure' or to help
2673 it to find libraries and programs with nonstandard names/locations.
2674
2675 Report bugs to the package provider.
