It's correct according to the docs, because djgpp.ver is not in what
GCC would recognizes as a "system include directory".

Here's some example output (reformatted for legible posting)
C:\My Documents\tmp>gcc -MM -v -c tt.c

End of search list.
tt.o: tt.c c:/djgpp/bin/../lib/gcc/djgpp/3.41/djgpp.ver

Unfortunately, adding the directory holding djgpp.ver to the system
include path list in any of the ways I tried (-I, -isystem, both with
and without the bin/.. sequence collapsed) didn't succeed in getting
it removed from the dependency output.  Andris?
