Hi Michael,

If you need to re-roll the patches in your 'mr/ff-refs' branch,
could you please squash parts of this patch into the relevant
patches from your branch.

Thanks.

Also, I note that gcc complains about the two calls to chdir().
(warning: ignoring return value of ‘chdir’, declared with
attribute warn_unused_result [-Wunused-result])

ATB,
Ramsay Jones
