 394 # For projects using AC_CONFIG_AUX_DIR([foo]), Autoconf sets
 395 # $ac_aux_dir to `$srcdir/foo'.  In other projects, it is set to
 396 # `$srcdir', `$srcdir/..', or `$srcdir/../..'.
 397 #
 398 # Of course, Automake must honor this variable whenever it calls a
 399 # tool from the auxiliary directory.  The problem is that $srcdir (and
 400 # therefore $ac_aux_dir as well) can be either absolute or relative,
 401 # depending on how configure is run.  This is pretty annoying, since
 402 # it makes $ac_aux_dir quite unusable in subdirectories: in the top
 403 # source directory, any form will work fine, but in subdirectories a
 404 # relative path needs to be adjusted first.
 405 #
 406 # $ac_aux_dir/missing
 407 #    fails when called from a subdirectory if $ac_aux_dir is relative
 408 # $top_srcdir/$ac_aux_dir/missing
 409 #    fails if $ac_aux_dir is absolute,
 410 #    fails when called from a subdirectory in a VPATH build with
 411 #          a relative $ac_aux_dir
 412 #
 413 # The reason of the latter failure is that $top_srcdir and $ac_aux_dir
 414 # are both prefixed by $srcdir.  In an in-source build this is usually
 415 # harmless because $srcdir is `.', but things will broke when you
 416 # start a VPATH build or use an absolute $srcdir.
 417 #
 418 # So we could use something similar to $top_srcdir/$ac_aux_dir/missing,
 419 # iff we strip the leading $srcdir from $ac_aux_dir.  That would be:
 420 #   am_aux_dir='\$(top_srcdir)/'`expr "$ac_aux_dir" : "$srcdir//*\(.*\)"`
 421 # and then we would define $MISSING as
 422 #   MISSING="\${SHELL} $am_aux_dir/missing"
 423 # This will work as long as MISSING is not called from configure, because
 424 # unfortunately $(top_srcdir) has no meaning in configure.
 425 # However there are other variables, like CC, which are often used in
 426 # configure, and could therefore not use this "fixed" $ac_aux_dir.
 427 #
 428 # Another solution, used here, is to always expand $ac_aux_dir to an
 429 # absolute PATH.  The drawback is that using absolute paths prevent a
 430 # configured tree to be moved without reconfiguration.
