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

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