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.
