c95639
#
c95639
# Of course, Automake must honor this variable whenever it calls a
c95639
# tool from the auxiliary directory.  The problem is that $srcdir (and
c95639
# therefore $ac_aux_dir as well) can be either absolute or relative,
c95639
# depending on how configure is run.  This is pretty annoying, since
c95639
# it makes $ac_aux_dir quite unusable in subdirectories: in the top
c95639
# source directory, any form will work fine, but in subdirectories a
c95639
# relative path needs to be adjusted first.
c95639

#    fails when called from a subdirectory if $ac_aux_dir is relative
c95639
# $top_srcdir/$ac_aux_dir/missing
c95639
#    fails if $ac_aux_dir is absolute,
c95639
#    fails when called from a subdirectory in a VPATH build with
c95639
#          a relative $ac_aux_dir
c95639
#
c95639
# The reason of the latter failure is that $top_srcdir and $ac_aux_dir
c95639
# are both prefixed by $srcdir.  In an in-source build this is usually
c95639
# harmless because $srcdir is '.', but things will broke when you
c95639
# start a VPATH build or use an absolute $srcdir.
c95639
#
c95639
# So we could use something similar to $top_srcdir/$ac_aux_dir/missing,
c95639
# iff we strip the leading $srcdir from $ac_aux_dir.  That would be:
c95639
#   am_aux_dir='\$(top_srcdir)/'`expr "$ac_aux_dir" : "$srcdir//*\(.*\)"`
c95639
# and then we would define $MISSING as
c95639
#   MISSING="\${SHELL} $am_aux_dir/missing"
c95639
# This will work as long as MISSING is not called from configure, because
c95639
# unfortunately $(top_srcdir) has no meaning in configure.
c95639
# However there are other variables, like CC, which are often used in
c95639
# configure, and could therefore not use this "fixed" $ac_aux_dir.
c95639
#
c95639
# Another solution, used here, is to always expand $ac_aux_dir to an
c95639
# absolute PATH.  The drawback is that using absolute paths prevent a
c95639
