It works fine for me on Linux, after I fixed your typo:

I realize that maybe this doesn't matter on Windows where the filesystem
is not case-sensitive, but of course on Linux if you delete "hello.c"
that won't have any impact on "Hello.c" which is why "Hello.c" still
exists after the "rm".

In your second example, with the subdirectory, you get the cases the
same:

> A makefile (makefile_sav) looking for files under a subfolder <test>
> works: (<test> contains hello.c and world.c files)
> 
> clean:
>         del test\hello.c

and it works.  I don't know enough about Windows to say if this case
difference really matters, but you might try that.

Please post a message on the address@hidden mailing list if you can't
figure it out: the folks on that list are a lot more knowledgeable about
make running on DOS/Windows platforms.
