| Older versions of GDB may not have start, in which case do "break main" then

|   Breakpoint 1 at 0x80485bc: file myprog.c, line 75.

|   ^Z^Z/home/nickrob/myprog.c:75:994:beg:0x80485bc

| 
| Z^Z/home/nickrob/octave/example.m:4

Sorry, but I'm not sure I follow exactly waht it is you want Octave to
do here.  Instead of making analogies with gdb, how about showing
precisely what Octave should do?

Also, I suspect that to be really useful inside Emacs' GUD mode,
Octave's debugging capabilities will need some improvement.  It would
be helpful to have someone who could work on that project.
