70# For projects using AC_CONFIG_AUX_DIR([foo]), Autoconf sets
71# $ac_aux_dir to '$srcdir/foo'.  In other projects, it is set to
72# '$srcdir', '$srcdir/..', or '$srcdir/../..'.
73#
74# Of course, Automake must honor this variable whenever it calls a
75# tool from the auxiliary directory.  The problem is that $srcdir (and
76# therefore $ac_aux_dir as well) can be either absolute or relative,
77# depending on how configure is run.  This is pretty annoying, since
78# it makes $ac_aux_dir quite unusable in subdirectories: in the top
79# source directory, any form will work fine, but in subdirectories a
80# relative path needs to be adjusted first.
81#
82# $ac_aux_dir/missing
83#    fails when called from a subdirectory if $ac_aux_dir is relative
84# $top_srcdir/$ac_aux_dir/missing
85#    fails if $ac_aux_dir is absolute,
86#    fails when called from a subdirectory in a VPATH build with
87#          a relative $ac_aux_dir
88#
89# The reason of the latter failure is that $top_srcdir and $ac_aux_dir
90# are both prefixed by $srcdir.  In an in-source build this is usually
91# harmless because $srcdir is '.', but things will broke when you
92# start a VPATH build or use an absolute $srcdir.
93#
94# So we could use something similar to $top_srcdir/$ac_aux_dir/missing,
95# iff we strip the leading $srcdir from $ac_aux_dir.  That would be:
96#   am_aux_dir='\$(top_srcdir)/'`expr "$ac_aux_dir" : "$srcdir//*\(.*\)"`
97# and then we would define $MISSING as
98#   MISSING="\${SHELL} $am_aux_dir/missing"
99# This will work as long as MISSING is not called from configure, because
100# unfortunately $(top_srcdir) has no meaning in configure.
101# However there are other variables, like CC, which are often used in
102# configure, and could therefore not use this "fixed" $ac_aux_dir.
103#
104# Another solution, used here, is to always expand $ac_aux_dir to an
105# absolute PATH.  The drawback is that using absolute paths prevent a
106# configured tree to be moved without reconfiguration.

949# AM_PROG_INSTALL_STRIP
950# ---------------------
951# One issue with vendor 'install' (even GNU) is that you can't
952# specify the program used to strip binaries.  This is especially
953# annoying in cross-compiling environments, where the build's strip
954# is unlikely to handle the host's binaries.
955# Fortunately install-sh will honor a STRIPPROG variable, so we
956# always use install-sh in "make install-strip", and initialize
957# STRIPPROG with the value of the STRIP variable (set by the user).
