94# For projects using AC_CONFIG_AUX_DIR([foo]), Autoconf sets
95# $ac_aux_dir to `$srcdir/foo'. In other projects, it is set to
96# `$srcdir', `$srcdir/..', or `$srcdir/../..'.
97#
98# Of course, Automake must honor this variable whenever it calls a
99# tool from the auxiliary directory. The problem is that $srcdir (and
100# therefore $ac_aux_dir as well) can be either absolute or relative,
101# depending on how configure is run. This is pretty annoying, since
102# it makes $ac_aux_dir quite unusable in subdirectories: in the top
103# source directory, any form will work fine, but in subdirectories a
104# relative path needs to be adjusted first.
105#
106# $ac_aux_dir/missing
107# fails when called from a subdirectory if $ac_aux_dir is relative
108# $top_srcdir/$ac_aux_dir/missing
109# fails if $ac_aux_dir is absolute,
110# fails when called from a subdirectory in a VPATH build with
111# a relative $ac_aux_dir
112#
113# The reason of the latter failure is that $top_srcdir and $ac_aux_dir
114# are both prefixed by $srcdir. In an in-source build this is usually
115# harmless because $srcdir is `.', but things will broke when you
116# start a VPATH build or use an absolute $srcdir.
117#
118# So we could use something similar to $top_srcdir/$ac_aux_dir/missing,
119# iff we strip the leading $srcdir from $ac_aux_dir. That would be:
120# am_aux_dir='\$(top_srcdir)/'`expr "$ac_aux_dir" : "$srcdir//*\(.*\)"`
121# and then we would define $MISSING as
122# MISSING="\${SHELL} $am_aux_dir/missing"
123# This will work as long as MISSING is not called from configure, because
124# unfortunately $(top_srcdir) has no meaning in configure.
125# However there are other variables, like CC, which are often used in
126# configure, and could therefore not use this "fixed" $ac_aux_dir.
127#
128# Another solution, used here, is to always expand $ac_aux_dir to an
129# absolute PATH. The drawback is that using absolute paths prevent a
130# configured tree to be moved without reconfiguration.

993# is unlikely to handle the host's binaries.
994# Fortunately install-sh will honor a STRIPPROG variable, so we
995# always use install-sh in `make install-strip', and initialize
996# STRIPPROG with the value of the STRIP variable (set by the user).
