bug report: cpp dependencies

[Marc-Peter.Schambach]

Hello.

gcc(cpp) produces a wrong *.d dependency file when compiling
preprocessed fortran *.F files:

The dependcy looks like this:
test.F.o: test.F test.h

instead of:
test.o: test.F test.h



Example:

> gcc -v

gcc version egcs-2.91.66 19990314/Linux (egcs-1.1.2 release)

> ls
test.F   test.h

> cat test.F
        program a
#include "test.h"
        print *, text
        END

> cat test.h
        character*(*) text
        parameter (text='Hello, Bug!')

> gcc -c -MMD test.F

> ls
test.F   test.d   test.h   test.o

> cat test.d
test.F.o: test.F test.h


>  gcc -v -c -MMD test.F
