! 184: #
! 185: # Of course, Automake must honor this variable whenever it calls a
! 186: # tool from the auxiliary directory. The problem is that $srcdir (and
! 187: # therefore $ac_aux_dir as well) can be either absolute or relative,
! 188: # depending on how configure is run. This is pretty annoying, since
! 189: # it makes $ac_aux_dir quite unusable in subdirectories: in the top
! 190: # source directory, any form will work fine, but in subdirectories a
! 191: # relative path needs to be adjusted first.

! 199: #
! 200: # The reason of the latter failure is that $top_srcdir and $ac_aux_dir
! 201: # are both prefixed by $srcdir. In an in-source build this is usually
! 202: # harmless because $srcdir is `.', but things will broke when you
! 203: # start a VPATH build or use an absolute $srcdir.
! 204: #
! 205: # So we could use something similar to $top_srcdir/$ac_aux_dir/missing,
! 206: # iff we strip the leading $srcdir from $ac_aux_dir. That would be:
! 207: # am_aux_dir='\$(top_srcdir)/'`expr "$ac_aux_dir" : "$srcdir//*\(.*\)"`
! 208: # and then we would define $MISSING as

! 213: # configure, and could therefore not use this "fixed" $ac_aux_dir.
! 214: #
! 215: # Another solution, used here, is to always expand $ac_aux_dir to an
