 267 # For projects using AC_CONFIG_AUX_DIR([foo]), Autoconf sets
 268 # $ac_aux_dir to '$srcdir/foo'.  In other projects, it is set to
 269 # '$srcdir', '$srcdir/..', or '$srcdir/../..'.
 270 #
 271 # Of course, Automake must honor this variable whenever it calls a
 272 # tool from the auxiliary directory.  The problem is that $srcdir (and
 273 # therefore $ac_aux_dir as well) can be either absolute or relative,
 274 # depending on how configure is run.  This is pretty annoying, since
 275 # it makes $ac_aux_dir quite unusable in subdirectories: in the top
 276 # source directory, any form will work fine, but in subdirectories a
 277 # relative path needs to be adjusted first.
 278 #
 279 # $ac_aux_dir/missing
 280 #    fails when called from a subdirectory if $ac_aux_dir is relative
 281 # $top_srcdir/$ac_aux_dir/missing
 282 #    fails if $ac_aux_dir is absolute,
 283 #    fails when called from a subdirectory in a VPATH build with
 284 #          a relative $ac_aux_dir
 285 #
 286 # The reason of the latter failure is that $top_srcdir and $ac_aux_dir
 287 # are both prefixed by $srcdir.  In an in-source build this is usually
 288 # harmless because $srcdir is '.', but things will broke when you
 289 # start a VPATH build or use an absolute $srcdir.
 290 #
 291 # So we could use something similar to $top_srcdir/$ac_aux_dir/missing,
 292 # iff we strip the leading $srcdir from $ac_aux_dir.  That would be:
 293 #   am_aux_dir='\$(top_srcdir)/'`expr "$ac_aux_dir" : "$srcdir//*\(.*\)"`
 294 # and then we would define $MISSING as
 295 #   MISSING="\${SHELL} $am_aux_dir/missing"
 296 # This will work as long as MISSING is not called from configure, because
 297 # unfortunately $(top_srcdir) has no meaning in configure.
 298 # However there are other variables, like CC, which are often used in
 299 # configure, and could therefore not use this "fixed" $ac_aux_dir.
 300 #
 301 # Another solution, used here, is to always expand $ac_aux_dir to an
 302 # absolute PATH.  The drawback is that using absolute paths prevent a
