 1493 \`configure' configures this package to adapt to many kinds of systems.
 1494 
 1495 Usage: $0 [OPTION]... [VAR=VALUE]...
 1496 
 1497 To assign environment variables (e.g., CC, CFLAGS...), specify them as
 1498 VAR=VALUE.  See below for descriptions of some of the useful variables.
 1499 
 1500 Defaults for the options are specified in brackets.
 1501 
 1502 Configuration:
 1503   -h, --help              display this help and exit
 1504       --help=short        display options specific to this package
 1505       --help=recursive    display the short help of all the included packages
 1506   -V, --version           display version information and exit
 1507   -q, --quiet, --silent   do not print \`checking ...' messages
 1508       --cache-file=FILE   cache test results in FILE [disabled]
 1509   -C, --config-cache      alias for \`--cache-file=config.cache'
 1510   -n, --no-create         do not create output files
 1511       --srcdir=DIR        find the sources in DIR [configure dir or \`..']
 1512 
 1513 Installation directories:
 1514   --prefix=PREFIX         install architecture-independent files in PREFIX
 1515                           [$ac_default_prefix]
 1516   --exec-prefix=EPREFIX   install architecture-dependent files in EPREFIX
 1517                           [PREFIX]
 1518 
 1519 By default, \`make install' will install all the files in
 1520 \`$ac_default_prefix/bin', \`$ac_default_prefix/lib' etc.  You can specify
 1521 an installation prefix other than \`$ac_default_prefix' using \`--prefix',
 1522 for instance \`--prefix=\$HOME'.
 1523 
 1524 For better control, use the options below.
 1525

 1527   --bindir=DIR            user executables [EPREFIX/bin]
 1528   --sbindir=DIR           system admin executables [EPREFIX/sbin]

 4480 # These exist entirely to fool aclocal when bootstrapping libtool.
 4481 #
 4482 # In the past libtool.m4 has provided macros via AC_DEFUN (or AU_DEFUN),
 4483 # which have later been changed to m4_define as they aren't part of the
 4484 # exported API, or moved to Autoconf or Automake where they belong.
 4485 #
 4486 # The trouble is, aclocal is a bit thick.  It'll see the old AC_DEFUN
 4487 # in /usr/share/aclocal/libtool.m4 and remember it, then when it sees us
 4488 # using a macro with the same name in our local m4/libtool.m4 it'll
 4489 # pull the old libtool.m4 in (it doesn't see our shiny new m4_define
 4490 # and doesn't know about Autoconf macros at all.)
 4491 #
 4492 # So we provide this file, which has a silly filename so it's always
 4493 # included after everything else.  This provides aclocal with the
 4494 # AC_DEFUNs it wants, but when m4 processes it, it doesn't do anything
 4495 # because those macros already exist, or will be overwritten later.
 4496 # We use AC_DEFUN over AU_DEFUN for compatibility with aclocal-1.6.
 4497 #
 4498 # Anytime we withdraw an AC_DEFUN or AU_DEFUN, remember to add it here.
 4499 # Yes, that means every name once taken will need to remain here until
 4500 # we give up compatibility with versions before 1.7, at which point
 4501 # we need to keep only those names which we still refer to.
 4502 
 4503 # This is to help aclocal find these macros, as it can't see m4_define.
