 339 # For projects using AC_CONFIG_AUX_DIR([foo]), Autoconf sets

 341 # '$srcdir', '$srcdir/..', or '$srcdir/../..'.
 342 #
 343 # Of course, Automake must honor this variable whenever it calls a
 344 # tool from the auxiliary directory.  The problem is that $srcdir (and
 345 # therefore $ac_aux_dir as well) can be either absolute or relative,
 346 # depending on how configure is run.  This is pretty annoying, since
 347 # it makes $ac_aux_dir quite unusable in subdirectories: in the top
 348 # source directory, any form will work fine, but in subdirectories a
 349 # relative path needs to be adjusted first.
 350 #
 351 # $ac_aux_dir/missing
 352 #    fails when called from a subdirectory if $ac_aux_dir is relative
 353 # $top_srcdir/$ac_aux_dir/missing
 354 #    fails if $ac_aux_dir is absolute,
 355 #    fails when called from a subdirectory in a VPATH build with
 356 #          a relative $ac_aux_dir
 357 #
 358 # The reason of the latter failure is that $top_srcdir and $ac_aux_dir
 359 # are both prefixed by $srcdir.  In an in-source build this is usually
 360 # harmless because $srcdir is '.', but things will broke when you
 361 # start a VPATH build or use an absolute $srcdir.
 362 #
 363 # So we could use something similar to $top_srcdir/$ac_aux_dir/missing,
 364 # iff we strip the leading $srcdir from $ac_aux_dir.  That would be:
 365 #   am_aux_dir='\$(top_srcdir)/'`expr "$ac_aux_dir" : "$srcdir//*\(.*\)"`
 366 # and then we would define $MISSING as
 367 #   MISSING="\${SHELL} $am_aux_dir/missing"
 368 # This will work as long as MISSING is not called from configure, because
 369 # unfortunately $(top_srcdir) has no meaning in configure.
 370 # However there are other variables, like CC, which are often used in
 371 # configure, and could therefore not use this "fixed" $ac_aux_dir.
 372 #
 373 # Another solution, used here, is to always expand $ac_aux_dir to an
 374 # absolute PATH.  The drawback is that using absolute paths prevent a

1323 # is unlikely to handle the host's binaries.
1324 # Fortunately install-sh will honor a STRIPPROG variable, so we
