After posting my response to Sven, I noticed that I hadn't read your post 
correctly.

I can reproduce his problems on a Windows XP Pro machine (with gcc 3.03):

C:\DOCUME~1\asu1\LOCALS~1\Temp>gcc -MM tmp.c
tmp.o: tmp.c c:/djgpp/lib/gcc-lib/djgpp/3.03/djgpp.ver

whereas you indicate this sould have complained about not being able to 
find <tmp.h>, and

C:\DOCUME~1\asu1\LOCALS~1\Temp>gcc -I. -MM tmp.c
tmp.o: tmp.c c:/djgpp/lib/gcc-lib/djgpp/3.03/djgpp.ver tmp3.h

whereas you mentioned this should only list djgpp.ver as a dependency.

Changing <tmp.h> to "tmp.c" yields the expected behavior.

Sorry I can't shed any light on to this.

Sinan.
