Whoah, that looks like a compiler bug to me! Rather than just removing this, 
I'd like to find out why it's happening at all and try to get it fixed.

The -MM switch (unlike -M) ought never to output dependencies for system 
headers. The only explanations I can think of is that either the compiler 
specs file (in djgpp/lib) is doing something really strange, or somewhere 
along the line somebody has included version.h, or another system header 
that then includes it, with the wrong sort of quotes ("" instead of <>). But 
I can't find any attempts to include version.h from Allegro headers, and in 
the djgpp headers it is only included twice, from go32.h and stdio.h, both 
of which use the <> syntax. Does this also hold true for your version? Which 
files in particular are being given this dependency?
