Surprisingly, the test suite did pass.  But I can't figure out which tests I 
should even expect to fail here.  A good test for this case needs to use some 
per-target flags to build two objects with different names from the same 
source.  Ideally it would set a -DINCLUDES1 or -DINCLUDES2 depending on which 
object is being built, and then have the source file include different header 
files.

Stefano, can you point me towards the correct tests to beef up here?  I can't 
promise when I'll get to it though.

In the meantime, I propose pushing the original patch (plus your formatting 
fixup) and then revisiting the "-MD,asdf.d" approach and tests afterwards.  
Does that sound reasonable?
