1264 \`configure' configures this package to adapt to many kinds of systems.

1266 Usage: $0 [OPTION]... [VAR=VALUE]...
1267
1268 To assign environment variables (e.g., CC, CFLAGS...), specify them as
1269 VAR=VALUE.  See below for descriptions of some of the useful variables.
1270
1271 Defaults for the options are specified in brackets.
1272
1273 Configuration:
1274   -h, --help              display this help and exit
1275       --help=short        display options specific to this package
1276       --help=recursive    display the short help of all the included packages
1277   -V, --version           display version information and exit
1278   -q, --quiet, --silent   do not print \`checking ...' messages
1279       --cache-file=FILE   cache test results in FILE [disabled]
1280   -C, --config-cache      alias for \`--cache-file=config.cache'
1281   -n, --no-create         do not create output files
1282       --srcdir=DIR        find the sources in DIR [configure dir or \`..']
1283
1284 Installation directories:
1285   --prefix=PREFIX         install architecture-independent files in PREFIX
1286                           [$ac_default_prefix]
1287   --exec-prefix=EPREFIX   install architecture-dependent files in EPREFIX
1288                           [PREFIX]
1289
1290 By default, \`make install' will install all the files in
1291 \`$ac_default_prefix/bin', \`$ac_default_prefix/lib' etc.  You can specify
1292 an installation prefix other than \`$ac_default_prefix' using \`--prefix',
1293 for instance \`--prefix=\$HOME'.
1294
1295 For better control, use the options below.

3556
3557 # These exist entirely to fool aclocal when bootstrapping libtool.
3558 #
3559 # In the past libtool.m4 has provided macros via AC_DEFUN (or AU_DEFUN)
3560 # which have later been changed to m4_define as they aren't part of the
3561 # exported API, or moved to Autoconf or Automake where they belong.
3562 #
3563 # The trouble is, aclocal is a bit thick.  It'll see the old AC_DEFUN
3564 # in /usr/share/aclocal/libtool.m4 and remember it, then when it sees us
3565 # using a macro with the same name in our local m4/libtool.m4 it'll
3566 # pull the old libtool.m4 in (it doesn't see our shiny new m4_define
3567 # and doesn't know about Autoconf macros at all.)
3568 #
3569 # So we provide this file, which has a silly filename so it's always
3570 # included after everything else.  This provides aclocal with the
3571 # AC_DEFUNs it wants, but when m4 processes it, it doesn't do anything
3572 # because those macros already exist, or will be overwritten later.
3573 # We use AC_DEFUN over AU_DEFUN for compatibility with aclocal-1.6.
3574 #
3575 # Anytime we withdraw an AC_DEFUN or AU_DEFUN, remember to add it here.
3576 # Yes, that means every name once taken will need to remain here until
3577 # we give up compatibility with versions before 1.7, at which point
3578 # we need to keep only those names which we still refer to.
3579
3580 # This is to help aclocal find these macros, as it can't see m4_define.

3811 # on the host system we'll have not only the same GCC version, but also
3812 # the same binutils version.

3814 # For build == host, search the same directories that the installed

3817 # criterion to tools (such as ar and ranlib) that are never invoked by
3818 # the compiler, to avoid mismatches.

3820 # Also note we have to check MD_EXEC_PREFIX before checking the user's path
3821 # if build == target.  This makes the most sense only when bootstrapping,
