Have you tried specifying the current working directory in Unix format
on the command line:
cc/include="./" humpf.c

?

I think I remember something like that being necessary for some
situation, but I'm not sure if it was this situation exactly.

Other than that, SET WATCH FILE is your friend for figuring out where
exactly the compiler is looking for the file it can't find.
