 222 # For projects using AC_CONFIG_AUX_DIR([foo]), Autoconf sets
 223 # $ac_aux_dir to `$srcdir/foo'.  In other projects, it is set to
 224 # `$srcdir', `$srcdir/..', or `$srcdir/../..'.
 225 #
 226 # Of course, Automake must honor this variable whenever it calls a
 227 # tool from the auxiliary directory.  The problem is that $srcdir (and
 228 # therefore $ac_aux_dir as well) can be either absolute or relative,
 229 # depending on how configure is run.  This is pretty annoying, since
 230 # it makes $ac_aux_dir quite unusable in subdirectories: in the top
 231 # source directory, any form will work fine, but in subdirectories a
 232 # relative path needs to be adjusted first.
 233 #
 234 # $ac_aux_dir/missing
 235 #    fails when called from a subdirectory if $ac_aux_dir is relative
 236 # $top_srcdir/$ac_aux_dir/missing
 237 #    fails if $ac_aux_dir is absolute,
 238 #    fails when called from a subdirectory in a VPATH build with
 239 #          a relative $ac_aux_dir
 240 #
 241 # The reason of the latter failure is that $top_srcdir and $ac_aux_dir
 242 # are both prefixed by $srcdir.  In an in-source build this is usually
 243 # harmless because $srcdir is `.', but things will broke when you
 244 # start a VPATH build or use an absolute $srcdir.
 245 #
 246 # So we could use something similar to $top_srcdir/$ac_aux_dir/missing,
 247 # iff we strip the leading $srcdir from $ac_aux_dir.  That would be:
 248 #   am_aux_dir='\$(top_srcdir)/'`expr "$ac_aux_dir" : "$srcdir//*\(.*\)"`
 249 # and then we would define $MISSING as
 250 #   MISSING="\${SHELL} $am_aux_dir/missing"
 251 # This will work as long as MISSING is not called from configure, because
 252 # unfortunately $(top_srcdir) has no meaning in configure.
 253 # However there are other variables, like CC, which are often used in
 254 # configure, and could therefore not use this "fixed" $ac_aux_dir.
 255 #
 256 # Another solution, used here, is to always expand $ac_aux_dir to an
 257 # absolute PATH.  The drawback is that using absolute paths prevent a
 258 # configured tree to be moved without reconfiguration.
