! 290: #
! 291: # Of course, Automake must honor this variable whenever it calls a

! 293: # therefore $ac_aux_dir as well) can be either absolute or relative,
! 294: # depending on how configure is run. This is pretty annoying, since
! 295: # it makes $ac_aux_dir quite unusable in subdirectories: in the top
! 296: # source directory, any form will work fine, but in subdirectories a
! 297: # relative path needs to be adjusted first.

! 303: # fails when called from a subdirectory in a VPATH build with

! 305: #
! 306: # The reason of the latter failure is that $top_srcdir and $ac_aux_dir
! 307: # are both prefixed by $srcdir. In an in-source build this is usually
! 308: # harmless because $srcdir is '.', but things will broke when you
! 309: # start a VPATH build or use an absolute $srcdir.
! 310: #
! 311: # So we could use something similar to $top_srcdir/$ac_aux_dir/missing,
! 312: # iff we strip the leading $srcdir from $ac_aux_dir. That would be:
! 313: # am_aux_dir='\$(top_srcdir)/'`expr "$ac_aux_dir" : "$srcdir//*\(.*\)"`
! 314: # and then we would define $MISSING as
! 315: # MISSING="\${SHELL} $am_aux_dir/missing"

! 319: # configure, and could therefore not use this "fixed" $ac_aux_dir.
