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

# This file is free software; the Free Software Foundation

# For projects using AC_CONFIG_AUX_DIR([foo]), Autoconf sets
# $ac_aux_dir to '$srcdir/foo'. In other projects, it is set to
# '$srcdir', '$srcdir/..', or '$srcdir/../..'.
#
# Of course, Automake must honor this variable whenever it calls a
# tool from the auxiliary directory. The problem is that $srcdir (and
# therefore $ac_aux_dir as well) can be either absolute or relative,
# depending on how configure is run. This is pretty annoying, since
# it makes $ac_aux_dir quite unusable in subdirectories: in the top
# source directory, any form will work fine, but in subdirectories a
# relative path needs to be adjusted first.
#
# $ac_aux_dir/missing
# fails when called from a subdirectory if $ac_aux_dir is relative
# $top_srcdir/$ac_aux_dir/missing
# fails if $ac_aux_dir is absolute,
# fails when called from a subdirectory in a VPATH build with
# a relative $ac_aux_dir
#
# The reason of the latter failure is that $top_srcdir and $ac_aux_dir
# are both prefixed by $srcdir. In an in-source build this is usually
# harmless because $srcdir is '.', but things will broke when you
# start a VPATH build or use an absolute $srcdir.
#
# So we could use something similar to $top_srcdir/$ac_aux_dir/missing,
# iff we strip the leading $srcdir from $ac_aux_dir. That would be:
# am_aux_dir='\$(top_srcdir)/'`expr "$ac_aux_dir" : "$srcdir//*\(.*\)"`
# and then we would define $MISSING as
# MISSING="\${SHELL} $am_aux_dir/missing"
# This will work as long as MISSING is not called from configure, because
# unfortunately $(top_srcdir) has no meaning in configure.
# However there are other variables, like CC, which are often used in
# configure, and could therefore not use this "fixed" $ac_aux_dir.
#
# Another solution, used here, is to always expand $ac_aux_dir to an
# absolute PATH. The drawback is that using absolute paths prevent a
# configured tree to be moved without reconfiguration.

Your 'rm' program seems unable to run without file operands specified

to the behaviour of most rm programs out there, and not conforming with
the upcoming POSIX standard: <http://austingroupbugs.net/view.php?id=542>

Aborting the configuration process, to ensure you take notice of the issue.
You can download and install GNU coreutils to get an 'rm' implementation
that behaves properly: <http://www.gnu.org/software/coreutils/>.
If you want to complete the configuration process using your problematic
'rm' anyway, export the environment variable ACCEPT_INFERIOR_RM_PROGRAM
to "yes", and re-run configure.
