Works, as advertized, for me.

Using your example, and not bothering to create "someotherfile.h".

         g++ -DHELLO_THERE -c testx.C
         In file included from testx.C:2:
         hello.h:3:27: someotherfile.h: No such file or directory

         g++ -c testx.C
         (No Errors returned)

This is with g++ 3.2.

Is it possible that you have another "hello.h"?
