2N/A# For projects using AC_CONFIG_AUX_DIR([foo]), Autoconf sets
2N/A# `$srcdir', `$srcdir/..', or `$srcdir/../..'.
2N/A# Of course, Automake must honor this variable whenever it calls a
2N/A# tool from the auxiliary directory. The problem is that $srcdir (and
2N/A# therefore $ac_aux_dir as well) can be either absolute or relative,
2N/A# depending on how configure is run. This is pretty annoying, since
2N/A# it makes $ac_aux_dir quite unusable in subdirectories: in the top
2N/A# source directory, any form will work fine, but in subdirectories a
2N/A# relative path needs to be adjusted first.
2N/A# fails when called from a subdirectory if $ac_aux_dir is relative
2N/A# fails if $ac_aux_dir is absolute,
2N/A# fails when called from a subdirectory in a VPATH build with
2N/A# a relative $ac_aux_dir
2N/A# The reason of the latter failure is that $top_srcdir and $ac_aux_dir
2N/A# are both prefixed by $srcdir. In an in-source build this is usually
2N/A# harmless because $srcdir is `.', but things will broke when you
2N/A# start a VPATH build or use an absolute $srcdir.
2N/A# iff we strip the leading $srcdir from $ac_aux_dir. That would be:
2N/A# am_aux_dir='\$(top_srcdir)/'`expr "$ac_aux_dir" : "$srcdir//*\(.*\)"`
2N/A# and then we would define $MISSING as
2N/A# This will work as long as MISSING is not called from configure, because
2N/A# unfortunately $(top_srcdir) has no meaning in configure.
2N/A# However there are other variables, like CC, which are often used in
2N/A# configure, and could therefore not use this "fixed" $ac_aux_dir.
2N/A# Another solution, used here, is to always expand $ac_aux_dir to an
2N/A# absolute PATH. The drawback is that using absolute paths prevent a
