6072	# For projects using AC_CONFIG_AUX_DIR([foo]), Autoconf sets
6073	# $ac_aux_dir to `$srcdir/foo'. In other projects, it is set to
6074	# `$srcdir', `$srcdir/..', or `$srcdir/../..'.
6075	#
6076	# Of course, Automake must honor this variable whenever it calls a
6077	# tool from the auxiliary directory. The problem is that $srcdir (and
6078	# therefore $ac_aux_dir as well) can be either absolute or relative,
6079	# depending on how configure is run. This is pretty annoying, since
6080	# it makes $ac_aux_dir quite unusable in subdirectories: in the top
6081	# source directory, any form will work fine, but in subdirectories a
6082	# relative path needs to be adjusted first.
6083	#
6084	# $ac_aux_dir/missing
6085	# fails when called from a subdirectory if $ac_aux_dir is relative
6086	# $top_srcdir/$ac_aux_dir/missing
6087	# fails if $ac_aux_dir is absolute,
6088	# fails when called from a subdirectory in a VPATH build with
6089	# a relative $ac_aux_dir
6090	#
6091	# The reason of the latter failure is that $top_srcdir and $ac_aux_dir
6092	# are both prefixed by $srcdir. In an in-source build this is usually
6093	# harmless because $srcdir is `.', but things will broke when you
6094	# start a VPATH build or use an absolute $srcdir.
6095	#
6096	# So we could use something similar to $top_srcdir/$ac_aux_dir/missing,
6097	# iff we strip the leading $srcdir from $ac_aux_dir. That would be:
6098	# am_aux_dir='\$(top_srcdir)/'`expr "$ac_aux_dir" : "$srcdir//\(.\)"`
6099	# and then we would define $MISSING as
6100	# MISSING="\${SHELL} $am_aux_dir/missing"
6101	# This will work as long as MISSING is not called from configure, because
6102	# unfortunately $(top_srcdir) has no meaning in configure.
6103	# However there are other variables, like CC, which are often used in
6104	# configure, and could therefore not use this "fixed" $ac_aux_dir.
6105	#
6106	# Another solution, used here, is to always expand $ac_aux_dir to an
6107	# absolute PATH. The drawback is that using absolute paths prevent a

6765	# ---------------------
6766	# One issue with vendor `install' (even GNU) is that you can't
6767	# specify the program used to strip binaries. This is especially
6768	# annoying in cross-compiling environments, where the build's strip
6769	# is unlikely to handle the host's binaries.
6770	# Fortunately install-sh will honor a STRIPPROG variable, so we
6771	# always use install-sh in `make install-strip', and initialize
6772	# STRIPPROG with the value of the STRIP variable (set by the user).
