916# Of course, Automake must honor this variable whenever it calls a

919# depending on how configure is run. This is pretty annoying, since
920# it makes $ac_aux_dir quite unusable in subdirectories: in the top
921# source directory, any form will work fine, but in subdirectories a
922# relative path needs to be adjusted first.
923#
924# $ac_aux_dir/missing
925# fails when called from a subdirectory if $ac_aux_dir is relative
926# $top_srcdir/$ac_aux_dir/missing
927# fails if $ac_aux_dir is absolute,
928# fails when called from a subdirectory in a VPATH build with
929# a relative $ac_aux_dir
930#
931# The reason of the latter failure is that $top_srcdir and $ac_aux_dir
932# are both prefixed by $srcdir. In an in-source build this is usually
7d32376a 933# harmless because $srcdir is '.', but things will broke when you
ab702381
DB
934# start a VPATH build or use an absolute $srcdir.
935#
936# So we could use something similar to $top_srcdir/$ac_aux_dir/missing,
937# iff we strip the leading $srcdir from $ac_aux_dir. That would be:
938# am_aux_dir='\$(top_srcdir)/'`expr "$ac_aux_dir" : "$srcdir//*\(.*\)"`
939# and then we would define $MISSING as
940# MISSING="\${SHELL} $am_aux_dir/missing"
941# This will work as long as MISSING is not called from configure, because
942# unfortunately $(top_srcdir) has no meaning in configure.
943# However there are other variables, like CC, which are often used in
944# configure, and could therefore not use this "fixed" $ac_aux_dir.
945#
946# Another solution, used here, is to always expand $ac_aux_dir to an
947# absolute PATH. The drawback is that using absolute paths prevent a
