The following session show my attempt to use the -gg option with gcc.
Note that when the breakpoint is hit the listing isn't of the main function
but is of the top of the source file. Note aalso the error message when
"step" is attempted. It doesn't seem to matter which source file I use. The
results are always the same.
Is this supposed to work?
