5640 *** reliably create shared libraries on SCO systems.  Therefore, libtool

5642 *** binutils to release 2.16.91.0.3 or newer.  Another option is to modify
5643 *** your PATH or compiler configuration so that the native linker is
5644 *** used, and then restart.

6465 # For projects using AC_CONFIG_AUX_DIR([foo]), Autoconf sets
6466 # $ac_aux_dir to `$srcdir/foo'.  In other projects, it is set to
6467 # `$srcdir', `$srcdir/..', or `$srcdir/../..'.
6468 #
6469 # Of course, Automake must honor this variable whenever it calls a
6470 # tool from the auxiliary directory.  The problem is that $srcdir (and
6471 # therefore $ac_aux_dir as well) can be either absolute or relative,
6472 # depending on how configure is run.  This is pretty annoying, since
6473 # it makes $ac_aux_dir quite unusable in subdirectories: in the top
6474 # source directory, any form will work fine, but in subdirectories a
6475 # relative path needs to be adjusted first.
6476 #
6477 # $ac_aux_dir/missing
6478 #    fails when called from a subdirectory if $ac_aux_dir is relative
6479 # $top_srcdir/$ac_aux_dir/missing
6480 #    fails if $ac_aux_dir is absolute,
6481 #    fails when called from a subdirectory in a VPATH build with
6482 #          a relative $ac_aux_dir
6483 #
6484 # The reason of the latter failure is that $top_srcdir and $ac_aux_dir
6485 # are both prefixed by $srcdir.  In an in-source build this is usually
6486 # harmless because $srcdir is `.', but things will broke when you
6487 # start a VPATH build or use an absolute $srcdir.
6488 #
6489 # So we could use something similar to $top_srcdir/$ac_aux_dir/missing,
6490 # iff we strip the leading $srcdir from $ac_aux_dir.  That would be:
6491 #   am_aux_dir='\$(top_srcdir)/'`expr "$ac_aux_dir" : "$srcdir//*\(.*\)"`
6492 # and then we would define $MISSING as
6493 #   MISSING="\${SHELL} $am_aux_dir/missing"
6494 # This will work as long as MISSING is not called from configure, because
6495 # unfortunately $(top_srcdir) has no meaning in configure.
6496 # However there are other variables, like CC, which are often used in
6497 # configure, and could therefore not use this "fixed" $ac_aux_dir.
6498 #
6499 # Another solution, used here, is to always expand $ac_aux_dir to an
6500 # absolute PATH.  The drawback is that using absolute paths prevent a
