2459 \`configure' configures libgnu UNUSED-VERSION to adapt to many kinds of systems.
2460
2461 Usage: $0 [OPTION]... [VAR=VALUE]...
2462
2463 To assign environment variables (e.g., CC, CFLAGS...), specify them as
2464 VAR=VALUE.  See below for descriptions of some of the useful variables.
2465
2466 Defaults for the options are specified in brackets.
2467
2468 Configuration:
2469   -h, --help              display this help and exit
2470       --help=short        display options specific to this package
2471       --help=recursive    display the short help of all the included packages
2472   -V, --version           display version information and exit
2473   -q, --quiet, --silent   do not print \`checking ...' messages
2474       --cache-file=FILE   cache test results in FILE [disabled]
2475   -C, --config-cache      alias for \`--cache-file=config.cache'
2476   -n, --no-create         do not create output files
2477       --srcdir=DIR        find the sources in DIR [configure dir or \`..']
2478
2479 Installation directories:
2480   --prefix=PREFIX         install architecture-independent files in PREFIX
2481                           [$ac_default_prefix]
2482   --exec-prefix=EPREFIX   install architecture-dependent files in EPREFIX
2483                           [PREFIX]
2484
2485 By default, \`make install' will install all the files in
2486 \`$ac_default_prefix/bin', \`$ac_default_prefix/lib' etc.  You can specify
2487 an installation prefix other than \`$ac_default_prefix' using \`--prefix',
2488 for instance \`--prefix=\$HOME'.
2489
2490 For better control, use the options below.

2557   CFLAGS      C compiler flags
2558   LDFLAGS     linker flags, e.g. -L<lib dir> if you have libraries in a

2560   LIBS        libraries to pass to the linker, e.g. -l<library>

2563   CPP         C preprocessor

30529 on the command line, even when the '-f' option is present.  This is contrary
