1567 \`configure' configures this package to adapt to many kinds of systems.

1569 Usage: $0 [OPTION]... [VAR=VALUE]...
1570
1571 To assign environment variables (e.g., CC, CFLAGS...), specify them as
1572 VAR=VALUE.  See below for descriptions of some of the useful variables.
1573
1574 Defaults for the options are specified in brackets.
1575
1576 Configuration:
1577   -h, --help              display this help and exit
1578       --help=short        display options specific to this package
1579       --help=recursive    display the short help of all the included packages
1580   -V, --version           display version information and exit
1581   -q, --quiet, --silent   do not print \`checking ...' messages
1582       --cache-file=FILE   cache test results in FILE [disabled]
1583   -C, --config-cache      alias for \`--cache-file=config.cache'
1584   -n, --no-create         do not create output files
1585       --srcdir=DIR        find the sources in DIR [configure dir or \`..']
1586
1587 Installation directories:
1588   --prefix=PREFIX         install architecture-independent files in PREFIX
1589                           [$ac_default_prefix]
1590   --exec-prefix=EPREFIX   install architecture-dependent files in EPREFIX
1591                           [PREFIX]
1592
1593 By default, \`make install' will install all the files in
1594 \`$ac_default_prefix/bin', \`$ac_default_prefix/lib' etc.  You can specify
1595 an installation prefix other than \`$ac_default_prefix' using \`--prefix',
1596 for instance \`--prefix=\$HOME'.

16709 *** Warning: Releases of the GNU linker prior to 2.16.91.0.3 can not
16710 *** reliably create shared libraries on SCO systems.  Therefore, libtool
16711 *** is disabling shared libraries support.  We urge you to upgrade GNU
16712 *** binutils to release 2.16.91.0.3 or newer.  Another option is to modify
16713 *** your PATH or compiler configuration so that the native linker is
16714 *** used, and then restart.
