2443 \`configure' configures libgnu UNUSED-VERSION to adapt to many kinds of systems.
2444
2445 Usage: $0 [OPTION]... [VAR=VALUE]...
2446
2447 To assign environment variables (e.g., CC, CFLAGS...), specify them as
2448 VAR=VALUE.  See below for descriptions of some of the useful variables.
2449
2450 Defaults for the options are specified in brackets.
2451
2452 Configuration:
2453   -h, --help              display this help and exit
2454       --help=short        display options specific to this package
2455       --help=recursive    display the short help of all the included packages
2456   -V, --version           display version information and exit
2457   -q, --quiet, --silent   do not print \`checking ...' messages
2458       --cache-file=FILE   cache test results in FILE [disabled]
2459   -C, --config-cache      alias for \`--cache-file=config.cache'
2460   -n, --no-create         do not create output files
2461       --srcdir=DIR        find the sources in DIR [configure dir or \`..']
2462
2463 Installation directories:
2464   --prefix=PREFIX         install architecture-independent files in PREFIX
2465                           [$ac_default_prefix]
2466   --exec-prefix=EPREFIX   install architecture-dependent files in EPREFIX
2467                           [PREFIX]
2468
2469 By default, \`make install' will install all the files in
2470 \`$ac_default_prefix/bin', \`$ac_default_prefix/lib' etc.  You can specify
2471 an installation prefix other than \`$ac_default_prefix' using \`--prefix',
2472 for instance \`--prefix=\$HOME'.
2473
2474 For better control, use the options below.

2539 Some influential environment variables:
2540   CC          C compiler command
2541   CFLAGS      C compiler flags
2542   LDFLAGS     linker flags, e.g. -L<lib dir> if you have libraries in a
2543               nonstandard directory <lib dir>
2544   LIBS        libraries to pass to the linker, e.g. -l<library>
2545   CPPFLAGS    (Objective) C/C++ preprocessor flags, e.g. -I<include dir> if
2546               you have headers in a nonstandard directory <include dir>
2547   CPP         C preprocessor
2548
2549 Use these variables to override the choices made by `configure' or to help
2550 it to find libraries and programs with nonstandard names/locations.

29803 Oops!
29804
29805 Your 'rm' program seems unable to run without file operands specified
29806 on the command line, even when the '-f' option is present.  This is contrary
29807 to the behaviour of most rm programs out there, and not conforming with
29808 the upcoming POSIX standard: <http://austingroupbugs.net/view.php?id=542>
29809
29810 Please tell bug-automake@gnu.org about your system, including the value
29811 of your $PATH and any error possibly output before this message.  This
29812 can help us improve future automake versions.
