346#
347# Of course, Automake must honor this variable whenever it calls a
348# tool from the auxiliary directory.  The problem is that $srcdir (and
349# therefore $ac_aux_dir as well) can be either absolute or relative,
350# depending on how configure is run.  This is pretty annoying, since
351# it makes $ac_aux_dir quite unusable in subdirectories: in the top
352# source directory, any form will work fine, but in subdirectories a
353# relative path needs to be adjusted first.
354#
355# $ac_aux_dir/missing
356#    fails when called from a subdirectory if $ac_aux_dir is relative
357# $top_srcdir/$ac_aux_dir/missing

359#    fails when called from a subdirectory in a VPATH build with
360#          a relative $ac_aux_dir
361#
362# The reason of the latter failure is that $top_srcdir and $ac_aux_dir
363# are both prefixed by $srcdir.  In an in-source build this is usually
364# harmless because $srcdir is '.', but things will broke when you
365# start a VPATH build or use an absolute $srcdir.
366#
367# So we could use something similar to $top_srcdir/$ac_aux_dir/missing,
368# iff we strip the leading $srcdir from $ac_aux_dir.  That would be:
369#   am_aux_dir='\$(top_srcdir)/'`expr "$ac_aux_dir" : "$srcdir//*\(.*\)"`
370# and then we would define $MISSING as
371#   MISSING="\${SHELL} $am_aux_dir/missing"
372# This will work as long as MISSING is not called from configure, because
373# unfortunately $(top_srcdir) has no meaning in configure.
374# However there are other variables, like CC, which are often used in
375# configure, and could therefore not use this "fixed" $ac_aux_dir.
376#
377# Another solution, used here, is to always expand $ac_aux_dir to an

1356# ---------------------
1357# One issue with vendor 'install' (even GNU) is that you can't
1358# specify the program used to strip binaries.  This is especially
1359# annoying in cross-compiling environments, where the build's strip
1360# is unlikely to handle the host's binaries.
1361# Fortunately install-sh will honor a STRIPPROG variable, so we
1362# always use install-sh in "make install-strip", and initialize
1363# STRIPPROG with the value of the STRIP variable (set by the user).
