87# For projects using AC_CONFIG_AUX_DIR([foo]), Autoconf sets
88# $ac_aux_dir to '$srcdir/foo'.  In other projects, it is set to
89# '$srcdir', '$srcdir/..', or '$srcdir/../..'.
90#
91# Of course, Automake must honor this variable whenever it calls a
92# tool from the auxiliary directory.  The problem is that $srcdir (and
93# therefore $ac_aux_dir as well) can be either absolute or relative,
94# depending on how configure is run.  This is pretty annoying, since
95# it makes $ac_aux_dir quite unusable in subdirectories: in the top
96# source directory, any form will work fine, but in subdirectories a
97# relative path needs to be adjusted first.
98#
99# $ac_aux_dir/missing
100#    fails when called from a subdirectory if $ac_aux_dir is relative
101# $top_srcdir/$ac_aux_dir/missing
102#    fails if $ac_aux_dir is absolute,
103#    fails when called from a subdirectory in a VPATH build with
104#          a relative $ac_aux_dir
105#
106# The reason of the latter failure is that $top_srcdir and $ac_aux_dir
107# are both prefixed by $srcdir.  In an in-source build this is usually
108# harmless because $srcdir is '.', but things will broke when you
109# start a VPATH build or use an absolute $srcdir.
110#
111# So we could use something similar to $top_srcdir/$ac_aux_dir/missing,
112# iff we strip the leading $srcdir from $ac_aux_dir.  That would be:
113#   am_aux_dir='\$(top_srcdir)/'`expr "$ac_aux_dir" : "$srcdir//*\(.*\)"`
114# and then we would define $MISSING as
115#   MISSING="\${SHELL} $am_aux_dir/missing"
116# This will work as long as MISSING is not called from configure, because
117# unfortunately $(top_srcdir) has no meaning in configure.
118# However there are other variables, like CC, which are often used in
119# configure, and could therefore not use this "fixed" $ac_aux_dir.
120#
121# Another solution, used here, is to always expand $ac_aux_dir to an
122# absolute PATH.  The drawback is that using absolute paths prevent a
123# configured tree to be moved without reconfiguration.
