133# For projects using AC_CONFIG_AUX_DIR([foo]), Autoconf sets
134# $ac_aux_dir to `$srcdir/foo'.  In other projects, it is set to
135# `$srcdir', `$srcdir/..', or `$srcdir/../..'.
136#
137# Of course, Automake must honor this variable whenever it calls a
138# tool from the auxiliary directory.  The problem is that $srcdir (and
139# therefore $ac_aux_dir as well) can be either absolute or relative,
140# depending on how configure is run.  This is pretty annoying, since
141# it makes $ac_aux_dir quite unusable in subdirectories: in the top
142# source directory, any form will work fine, but in subdirectories a
143# relative path needs to be adjusted first.
144#
145# $ac_aux_dir/missing
146#    fails when called from a subdirectory if $ac_aux_dir is relative
147# $top_srcdir/$ac_aux_dir/missing
148#    fails if $ac_aux_dir is absolute,
149#    fails when called from a subdirectory in a VPATH build with
150#          a relative $ac_aux_dir
151#
152# The reason of the latter failure is that $top_srcdir and $ac_aux_dir
153# are both prefixed by $srcdir.  In an in-source build this is usually
154# harmless because $srcdir is `.', but things will broke when you
155# start a VPATH build or use an absolute $srcdir.
156#
157# So we could use something similar to $top_srcdir/$ac_aux_dir/missing,
158# iff we strip the leading $srcdir from $ac_aux_dir.  That would be:
159#   am_aux_dir='\$(top_srcdir)/'`expr "$ac_aux_dir" : "$srcdir//*\(.*\)"`
160# and then we would define $MISSING as
161#   MISSING="\${SHELL} $am_aux_dir/missing"
162# This will work as long as MISSING is not called from configure, because
163# unfortunately $(top_srcdir) has no meaning in configure.
164# However there are other variables, like CC, which are often used in
165# configure, and could therefore not use this "fixed" $ac_aux_dir.
166#
167# Another solution, used here, is to always expand $ac_aux_dir to an
168# absolute PATH.  The drawback is that using absolute paths prevent a
169# configured tree to be moved without reconfiguration.

938# specify the program used to strip binaries.  This is especially
939# annoying in cross-compiling environments, where the build's strip
940# is unlikely to handle the host's binaries.
941# Fortunately install-sh will honor a STRIPPROG variable, so we
942# always use install-sh in `make install-strip', and initialize
943# STRIPPROG with the value of the STRIP variable (set by the user).
