Uoti just confirmed my initial suspicion after I ported this over
to MPlayer: This change is not equivalent.

The reason I made this change in the first place was to have .d files
updated when any of the files the .c file depends on changes.  This was
to reflect changing header inclusions, etc.  This no longer works.  Try
touching a header file and running make, .d files will not get updated
even though they could be affected.
