 1435 \`configure' configures xfe 1.43.2 to adapt to many kinds of systems.
 1436 
 1437 Usage: $0 [OPTION]... [VAR=VALUE]...
 1438 
 1439 To assign environment variables (e.g., CC, CFLAGS...), specify them as
 1440 VAR=VALUE.  See below for descriptions of some of the useful variables.
 1441 
 1442 Defaults for the options are specified in brackets.
 1443 
 1444 Configuration:
 1445   -h, --help              display this help and exit
 1446       --help=short        display options specific to this package
 1447       --help=recursive    display the short help of all the included packages
 1448   -V, --version           display version information and exit
 1449   -q, --quiet, --silent   do not print \`checking ...' messages
 1450       --cache-file=FILE   cache test results in FILE [disabled]
 1451   -C, --config-cache      alias for \`--cache-file=config.cache'
 1452   -n, --no-create         do not create output files
 1453       --srcdir=DIR        find the sources in DIR [configure dir or \`..']
 1454 
 1455 Installation directories:
 1456   --prefix=PREFIX         install architecture-independent files in PREFIX
 1457                           [$ac_default_prefix]
 1458   --exec-prefix=EPREFIX   install architecture-dependent files in EPREFIX
 1459                           [PREFIX]
 1460 
 1461 By default, \`make install' will install all the files in
 1462 \`$ac_default_prefix/bin', \`$ac_default_prefix/lib' etc.  You can specify
 1463 an installation prefix other than \`$ac_default_prefix' using \`--prefix',
 1464 for instance \`--prefix=\$HOME'.
 1465 
 1466 For better control, use the options below.
 1467 
 1468 Fine tuning of the installation directories:
 1469   --bindir=DIR            user executables [EPREFIX/bin]

 3493 # actually supported "in the wild" to an acceptable degree.
 3494 # See automake bug#10828.

 3500 Oops!
 3501 
 3502 Your 'rm' program seems unable to run without file operands specified
 3503 on the command line, even when the '-f' option is present.  This is contrary
 3504 to the behaviour of most rm programs out there, and not conforming with
 3505 the upcoming POSIX standard: <http://austingroupbugs.net/view.php?id=542>
 3506 
 3507 Please tell bug-automake@gnu.org about your system, including the value
 3508 of your $PATH and any error possibly output before this message.  This
 3509 can help us improve future automake versions.
