# For projects using AC_CONFIG_AUX_DIR([foo]), Autoconf sets
89
# $ac_aux_dir to `$srcdir/foo'.  In other projects, it is set to
90
# `$srcdir', `$srcdir/..', or `$srcdir/../..'.
91
#
92
# Of course, Automake must honor this variable whenever it calls a
93
# tool from the auxiliary directory.  The problem is that $srcdir (and
94
# therefore $ac_aux_dir as well) can be either absolute or relative,
95
# depending on how configure is run.  This is pretty annoying, since
96
# it makes $ac_aux_dir quite unusable in subdirectories: in the top
97
# source directory, any form will work fine, but in subdirectories a
98
# relative path needs to be adjusted first.
99
#
100
# $ac_aux_dir/missing
101
#    fails when called from a subdirectory if $ac_aux_dir is relative
102
# $top_srcdir/$ac_aux_dir/missing
103
#    fails if $ac_aux_dir is absolute,
104
#    fails when called from a subdirectory in a VPATH build with
105
#          a relative $ac_aux_dir
106
#
107
# The reason of the latter failure is that $top_srcdir and $ac_aux_dir
108
# are both prefixed by $srcdir.  In an in-source build this is usually
109
# harmless because $srcdir is `.', but things will broke when you
110
# start a VPATH build or use an absolute $srcdir.
111
#
112
# So we could use something similar to $top_srcdir/$ac_aux_dir/missing,
113
# iff we strip the leading $srcdir from $ac_aux_dir.  That would be:
114
#   am_aux_dir='\$(top_srcdir)/'`expr "$ac_aux_dir" : "$srcdir//*\(.*\)"`
115
# and then we would define $MISSING as
116
#   MISSING="\${SHELL} $am_aux_dir/missing"
117
# This will work as long as MISSING is not called from configure, because
118
# unfortunately $(top_srcdir) has no meaning in configure.
119
# However there are other variables, like CC, which are often used in
120
# configure, and could therefore not use this "fixed" $ac_aux_dir.
121
#
122
# Another solution, used here, is to always expand $ac_aux_dir to an
123
# absolute PATH.  The drawback is that using absolute paths prevent a
124
# configured tree to be moved without reconfiguration.
