        * m4/auxdir.m4 (AM_AUX_DIR_EXPAND): Divert output from 'cd' to
        /dev/null to avoid filling $am_aux_dir with garbage that propagates
        into sed-scripts in config.status. Problem triggers on MacOS X when
        srcdir equals builddir.

 # Another solution, used here, is to always expand $ac_aux_dir to an
 # absolute PATH.  The drawback is that using absolute paths prevent a
 # configured tree to be moved without reconfiguration.
+# Note that "cd $auxdir" will output the path on MacOS X, and must be
+# redirected to /dev/null to avoid filling am_aux_dir with garbage that
+# ends up destroying the sed scripts in config.status.
