66# For projects using AC_CONFIG_AUX_DIR([foo]), Autoconf sets
67# $ac_aux_dir to `$srcdir/foo'.  In other projects, it is set to
68# `$srcdir', `$srcdir/..', or `$srcdir/../..'.
69#
70# Of course, Automake must honor this variable whenever it calls a
71# tool from the auxiliary directory.  The problem is that $srcdir (and
72# therefore $ac_aux_dir as well) can be either absolute or relative,
73# depending on how configure is run.  This is pretty annoying, since
74# it makes $ac_aux_dir quite unusable in subdirectories: in the top
75# source directory, any form will work fine, but in subdirectories a
76# relative path needs to be adjusted first.
77#
78# $ac_aux_dir/missing
79#    fails when called from a subdirectory if $ac_aux_dir is relative
80# $top_srcdir/$ac_aux_dir/missing
81#    fails if $ac_aux_dir is absolute,
82#    fails when called from a subdirectory in a VPATH build with
83#          a relative $ac_aux_dir
84#
85# The reason of the latter failure is that $top_srcdir and $ac_aux_dir
86# are both prefixed by $srcdir.  In an in-source build this is usually
87# harmless because $srcdir is `.', but things will broke when you
88# start a VPATH build or use an absolute $srcdir.
89#
90# So we could use something similar to $top_srcdir/$ac_aux_dir/missing,
91# iff we strip the leading $srcdir from $ac_aux_dir.  That would be:
92#   am_aux_dir='\$(top_srcdir)/'`expr "$ac_aux_dir" : "$srcdir//*\(.*\)"`
93# and then we would define $MISSING as
94#   MISSING="\${SHELL} $am_aux_dir/missing"
95# This will work as long as MISSING is not called from configure, because
96# unfortunately $(top_srcdir) has no meaning in configure.
97# However there are other variables, like CC, which are often used in
98# configure, and could therefore not use this "fixed" $ac_aux_dir.
99#
100# Another solution, used here, is to always expand $ac_aux_dir to an
101# absolute PATH.  The drawback is that using absolute paths prevent a
102# configured tree to be moved without reconfiguration.
