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
