I have four files: 
   c:\djgpp\include\tmp.h contains:
     #include "tmp2.h"
     #include "tmp3.h"
   c:\djgpp\include\tmp2.h is empty
   c:\djgpp\include\tmp3.h is empty
   tmp.c contains:
      #include <tmp.h> 

If I run

   gcc -MM tmp.c

I get the output

   tmp.o: tmp.c c:/djgpp/lib/gcc-lib/djgpp/3.03/djgpp.ver \
     c:/djgpp/include/tmp3.h

Why does it depend on tmp3.h but not tmp2.h? I think it shouldn't depend
on any of them, because it is written <tmp.h>, not "tmp.h", and I use
-MM.

I have a plain vanilla djgpp installtion (i.e., haven't hacked djgpp.env
or specs or anything like that). gcc -v gives:

Reading specs from c:/djgpp/lib/gcc-lib/djgpp/3.03/specs
Configured with: ../configure i586-pc-msdosdjgpp --prefix=/dev/env/DJDIR
