dnl
dnl Introduces an --enable-optionname/--disable-optionname flag pair for a

dnl disabled depending on whether or not dependency-checks succeed or fail.
dnl If --enable-optionname is provided, the configure script will error out if
dnl the dependencies are not met. If --disable-optionname is provided, the
dnl feature will be disabled, and dependencies will not be checked.

dnl The dependency-checks argument should be a series of
dnl XDT_FEATURE_DEPENDENCY() macro calls, passed as a single quoted argument to
dnl XDT_CHECK_OPTIONAL_FEATURE().
dnl
dnl If helpstring is not provided, optionname is used instead.
dnl
dnl The default is "auto", and semantics are as described above. If default is
dnl set to "yes", then the feature will be required unless --disable-optionname
dnl is passed to configure. If default is set to "no", the feature will not be
dnl built unless --enable-optionname is passed.
dnl
dnl If the feature is enabled and dependencies are met, ENABLE_varname will be
dnl defined in config.h. Additionally, an automake conditional called
dnl ENABLE_varname will be created, and a shell variable called ENABLE_varname

#
# 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
on the command line, even when the '-f' option is present. This is contrary
to the behaviour of most rm programs out there, and not conforming with
the upcoming POSIX standard: <http://austingroupbugs.net/view.php?id=542>
