 316 # For projects using AC_CONFIG_AUX_DIR([foo]), Autoconf sets
 317 # $ac_aux_dir to `$srcdir/foo'.  In other projects, it is set to
 318 # `$srcdir', `$srcdir/..', or `$srcdir/../..'.
 319 #
 320 # Of course, Automake must honor this variable whenever it calls a
 321 # tool from the auxiliary directory.  The problem is that $srcdir (and
 322 # therefore $ac_aux_dir as well) can be either absolute or relative,
 323 # depending on how configure is run.  This is pretty annoying, since
 324 # it makes $ac_aux_dir quite unusable in subdirectories: in the top
 325 # source directory, any form will work fine, but in subdirectories a
 326 # relative path needs to be adjusted first.
 327 #
 328 # $ac_aux_dir/missing
 329 #    fails when called from a subdirectory if $ac_aux_dir is relative
 330 # $top_srcdir/$ac_aux_dir/missing
 331 #    fails if $ac_aux_dir is absolute,
 332 #    fails when called from a subdirectory in a VPATH build with
 333 #          a relative $ac_aux_dir
 334 #
 335 # The reason of the latter failure is that $top_srcdir and $ac_aux_dir
 336 # are both prefixed by $srcdir.  In an in-source build this is usually
 337 # harmless because $srcdir is `.', but things will broke when you
 338 # start a VPATH build or use an absolute $srcdir.
 339 #
 340 # So we could use something similar to $top_srcdir/$ac_aux_dir/missing,
 341 # iff we strip the leading $srcdir from $ac_aux_dir.  That would be:
 342 #   am_aux_dir='\$(top_srcdir)/'`expr "$ac_aux_dir" : "$srcdir//*\(.*\)"`
 343 # and then we would define $MISSING as
 344 #   MISSING="\${SHELL} $am_aux_dir/missing"
 345 # This will work as long as MISSING is not called from configure, because
 346 # unfortunately $(top_srcdir) has no meaning in configure.
 347 # However there are other variables, like CC, which are often used in
 348 # configure, and could therefore not use this "fixed" $ac_aux_dir.
 349 #
 350 # Another solution, used here, is to always expand $ac_aux_dir to an
 351 # absolute PATH.  The drawback is that using absolute paths prevent a
 352 # configured tree to be moved without reconfiguration.
