 282 # For projects using AC_CONFIG_AUX_DIR([foo]), Autoconf sets
 283 # $ac_aux_dir to '$srcdir/foo'.  In other projects, it is set to
 284 # '$srcdir', '$srcdir/..', or '$srcdir/../..'.
 285 #
 286 # Of course, Automake must honor this variable whenever it calls a
 287 # tool from the auxiliary directory.  The problem is that $srcdir (and
 288 # therefore $ac_aux_dir as well) can be either absolute or relative,
 289 # depending on how configure is run.  This is pretty annoying, since
 290 # it makes $ac_aux_dir quite unusable in subdirectories: in the top
 291 # source directory, any form will work fine, but in subdirectories a
 292 # relative path needs to be adjusted first.
 293 #
 294 # $ac_aux_dir/missing
 295 #    fails when called from a subdirectory if $ac_aux_dir is relative
 296 # $top_srcdir/$ac_aux_dir/missing
 297 #    fails if $ac_aux_dir is absolute,
 298 #    fails when called from a subdirectory in a VPATH build with
 299 #          a relative $ac_aux_dir
 300 #
 301 # The reason of the latter failure is that $top_srcdir and $ac_aux_dir
 302 # are both prefixed by $srcdir.  In an in-source build this is usually
 303 # harmless because $srcdir is '.', but things will broke when you
 304 # start a VPATH build or use an absolute $srcdir.
 305 #
 306 # So we could use something similar to $top_srcdir/$ac_aux_dir/missing,
 307 # iff we strip the leading $srcdir from $ac_aux_dir.  That would be:
 308 #   am_aux_dir='\$(top_srcdir)/'`expr "$ac_aux_dir" : "$srcdir//*\(.*\)"`
 309 # and then we would define $MISSING as
 310 #   MISSING="\${SHELL} $am_aux_dir/missing"
 311 # This will work as long as MISSING is not called from configure, because
 312 # unfortunately $(top_srcdir) has no meaning in configure.
 313 # However there are other variables, like CC, which are often used in
 314 # configure, and could therefore not use this "fixed" $ac_aux_dir.
 315 #
 316 # Another solution, used here, is to always expand $ac_aux_dir to an
 317 # absolute PATH.  The drawback is that using absolute paths prevent a
