Yes, your example does indeed work.  Mine probably did as well, and I
admit that I didn't test that.  My real problem is much more
complicated with a number of OMakefiles in different subdirectories.
But I only have a single implicit rule for compiling C files.  I will
investigate further, now that I know that I'm on the right track.
