2414 \`configure' configures libgnu UNUSED-VERSION to adapt to many kinds of systems.
2415
2416 Usage: $0 [OPTION]... [VAR=VALUE]...
2417
2418 To assign environment variables (e.g., CC, CFLAGS...), specify them as
2419 VAR=VALUE.  See below for descriptions of some of the useful variables.
2420
2421 Defaults for the options are specified in brackets.
2422
2423 Configuration:
2424   -h, --help              display this help and exit
2425       --help=short        display options specific to this package
2426       --help=recursive    display the short help of all the included packages
2427   -V, --version           display version information and exit
2428   -q, --quiet, --silent   do not print \`checking ...' messages
2429       --cache-file=FILE   cache test results in FILE [disabled]
2430   -C, --config-cache      alias for \`--cache-file=config.cache'
2431   -n, --no-create         do not create output files
2432       --srcdir=DIR        find the sources in DIR [configure dir or \`..']
2433
2434 Installation directories:
2435   --prefix=PREFIX         install architecture-independent files in PREFIX
2436                           [$ac_default_prefix]
2437   --exec-prefix=EPREFIX   install architecture-dependent files in EPREFIX
2438                           [PREFIX]
2439
2440 By default, \`make install' will install all the files in
2441 \`$ac_default_prefix/bin', \`$ac_default_prefix/lib' etc.  You can specify
2442 an installation prefix other than \`$ac_default_prefix' using \`--prefix',
2443 for instance \`--prefix=\$HOME'.
2444
2445 For better control, use the options below.

2510 Some influential environment variables:
2511   CC          C compiler command
2512   CFLAGS      C compiler flags
2513   LDFLAGS     linker flags, e.g. -L<lib dir> if you have libraries in a
2514               nonstandard directory <lib dir>
2515   LIBS        libraries to pass to the linker, e.g. -l<library>
2516   CPPFLAGS    (Objective) C/C++ preprocessor flags, e.g. -I<include dir> if
2517               you have headers in a nonstandard directory <include dir>
2518   CPP         C preprocessor
2519
2520 Use these variables to override the choices made by `configure' or to help
2521 it to find libraries and programs with nonstandard names/locations.

27692 Your 'rm' program seems unable to run without file operands specified
27693 on the command line, even when the '-f' option is present.  This is contrary
27694 to the behaviour of most rm programs out there, and not conforming with
27695 the upcoming POSIX standard: <http://austingroupbugs.net/view.php?id=542>
