Hi,
(restoring cc list. Unfortunately gmane's web interface doesn't
provide a built-in way to reply-to-all. [1] has a hackish

Seems to have been fixed by v3.0pre0~187:
commit e8354384
Author: Andrea Bittau <a.bittau@xxxxxxxxxxxx>

Fix handling of the -MD and -MDD options
From <http://lists.samba.org/archive/ccache/2007q2/000272.html>:
The -MD and -MDD options automatically determine where the dependency file
should land and what the target should look like based on the -o option.
However, ccache drops -o and things mess up. The original patch was posted by
Kaz Kylheku but I reworked it to make it work properly. Here is his post:

Workaround incoming in a few moments.
Thanks,
Jonathan
