2555 \`configure' configures libgnu UNUSED-VERSION to adapt to many kinds of systems.
2556
2557 Usage: $0 [OPTION]... [VAR=VALUE]...
2558
2559 To assign environment variables (e.g., CC, CFLAGS...), specify them as
2560 VAR=VALUE. See below for descriptions of some of the useful variables.
2561
2562 Defaults for the options are specified in brackets.
2563
2564 Configuration:
2565 -h, --help display this help and exit
2566 --help=short display options specific to this package
2567 --help=recursive display the short help of all the included packages
2568 -V, --version display version information and exit
2569 -q, --quiet, --silent do not print \`checking ...' messages
2570 --cache-file=FILE cache test results in FILE [disabled]
2571 -C, --config-cache alias for \`--cache-file=config.cache'
2572 -n, --no-create do not create output files
2573 --srcdir=DIR find the sources in DIR [configure dir or \`..']
2574
2575 Installation directories:
2576 --prefix=PREFIX install architecture-independent files in PREFIX
2577 [$ac_default_prefix]
2578 --exec-prefix=EPREFIX install architecture-dependent files in EPREFIX
2579 [PREFIX]
2580
2581 By default, \`make install' will install all the files in
2582 \`$ac_default_prefix/bin', \`$ac_default_prefix/lib' etc. You can specify
2583 an installation prefix other than \`$ac_default_prefix' using \`--prefix',
2584 for instance \`--prefix=\$HOME'.
2585
2586 For better control, use the options below.

2588 Fine tuning of the installation directories:
2589 --bindir=DIR user executables [EPREFIX/bin]

2651 Some influential environment variables:
2652 CC C compiler command
2653 CFLAGS C compiler flags
2654 LDFLAGS linker flags, e.g. -L<lib dir> if you have libraries in a
2655 nonstandard directory <lib dir>
2656 LIBS libraries to pass to the linker, e.g. -l<library>
2657 CPPFLAGS (Objective) C/C++ preprocessor flags, e.g. -I<include dir> if
2658 you have headers in a nonstandard directory <include dir>
2659 CPP C preprocessor
2660
2661 Use these variables to override the choices made by `configure' or to help
2662 it to find libraries and programs with nonstandard names/locations.
2663
2664 Report bugs to the package provider.

31401 Oops!
31402
31403 Your 'rm' program seems unable to run without file operands specified
31404 on the command line, even when the '-f' option is present. This is contrary
31405 to the behaviour of most rm programs out there, and not conforming with
31406 the upcoming POSIX standard: <http://austingroupbugs.net/view.php?id=542>
31407
31408 Please tell bug-automake@gnu.org about your system, including the value
31409 of your $PATH and any error possibly output before this message. This
31410 can help us improve future automake versions.
