     67# For projects using AC_CONFIG_AUX_DIR([foo]), Autoconf sets
     68# $ac_aux_dir to '$srcdir/foo'.  In other projects, it is set to
     69# '$srcdir', '$srcdir/..', or '$srcdir/../..'.
     70#
     71# Of course, Automake must honor this variable whenever it calls a
     72# tool from the auxiliary directory.  The problem is that $srcdir (and
     73# therefore $ac_aux_dir as well) can be either absolute or relative,
     74# depending on how configure is run.  This is pretty annoying, since
     75# it makes $ac_aux_dir quite unusable in subdirectories: in the top
     76# source directory, any form will work fine, but in subdirectories a
     77# relative path needs to be adjusted first.
     78#
     79# $ac_aux_dir/missing
     80#    fails when called from a subdirectory if $ac_aux_dir is relative
     81# $top_srcdir/$ac_aux_dir/missing
     82#    fails if $ac_aux_dir is absolute,
     83#    fails when called from a subdirectory in a VPATH build with
     84#          a relative $ac_aux_dir
     85#
     86# The reason of the latter failure is that $top_srcdir and $ac_aux_dir
     87# are both prefixed by $srcdir.  In an in-source build this is usually
     88# harmless because $srcdir is '.', but things will broke when you
     89# start a VPATH build or use an absolute $srcdir.
     90#
     91# So we could use something similar to $top_srcdir/$ac_aux_dir/missing,
     92# iff we strip the leading $srcdir from $ac_aux_dir.  That would be:
     93#   am_aux_dir='\$(top_srcdir)/'`expr "$ac_aux_dir" : "$srcdir//*\(.*\)"`
     94# and then we would define $MISSING as
     95#   MISSING="\${SHELL} $am_aux_dir/missing"
     96# This will work as long as MISSING is not called from configure, because
     97# unfortunately $(top_srcdir) has no meaning in configure.
     98# However there are other variables, like CC, which are often used in
     99# configure, and could therefore not use this "fixed" $ac_aux_dir.
    100#
    101# Another solution, used here, is to always expand $ac_aux_dir to an
    102# absolute PATH.  The drawback is that using absolute paths prevent a
    103# configured tree to be moved without reconfiguration.
