6037#    fails when called from a subdirectory in a VPATH build with
6038#          a relative $ac_aux_dir
6039#
6040# The reason of the latter failure is that $top_srcdir and $ac_aux_dir
6041# are both prefixed by $srcdir.  In an in-source build this is usually
6042# harmless because $srcdir is `.', but things will broke when you
6043# start a VPATH build or use an absolute $srcdir.
6044#
6045# So we could use something similar to $top_srcdir/$ac_aux_dir/missing,
6046# iff we strip the leading $srcdir from $ac_aux_dir.  That would be:
6047#   am_aux_dir='\$(top_srcdir)/'`expr "$ac_aux_dir" : "$srcdir//*\(.*\)"`
6048# and then we would define $MISSING as
6049#   MISSING="\${SHELL} $am_aux_dir/missing"
6050# This will work as long as MISSING is not called from configure, because
6051# unfortunately $(top_srcdir) has no meaning in configure.
6052# However there are other variables, like CC, which are often used in
6053# configure, and could therefore not use this "fixed" $ac_aux_dir.
6054#
6055# Another solution, used here, is to always expand $ac_aux_dir to an
6056# absolute PATH.  The drawback is that using absolute paths prevent a
6057# configured tree to be moved without reconfiguration.
