I think the problem may have been that I was not using noweb (or
indent), and there was a slight mismatch between the .nw and .c files.

GDB was able to find the .nw files (as that was what the debug
information was pointing to), but the lines were off a bit. This meant
that most of the breakpoint commands (ones that did not rely on the
function entry points, but instead on line-to-address mappings) didn't
work.

I agree that it "should" work, since this is what the C preprocessor
uses to map back to un-preprocessed line numbers...
