And I strongly suggest that you ensure that WinAVR's make is used to build
your projects, as it is known to work without issue.

I've been keeping an eye on this thread and I've already worked in the
different compiler flag to generate dependencies with relative paths into
the Makefile Template. Thanks to you both for highlighting this issue and
thanks Dave for providing a solution! It's very appreciate.

FYI, Mfile started off, and still uses, the WinAVR Makefile Template
(located in <install>\sample\Makefile). Joerg and I work together on
Makefile Template to make sure that it works well with both Mfile, and as an
independently used makefile.
