I'm not sure what is the current behavior in Emacs and what is "standard".
Does it simply always open a new dinwo showing the file that contains
`main'?  If so, I find it inconvenient.

Maybe it's OK in other GUI debuggers because their environment is different:
they probably always have one source-code-view window, so they may as well
show the `main' function rather than keep the window empty.

The splitting for *gud* is another independent issue.  I'd rather focus on
the issue at hand which is the fact that the file holding the `main'
function is displayed.

Also this is another independent issue: how to turn on gud-minor-mode in
the right buffers.  It's a difficult question, but I'd rather avoid it for
now, lest we get lost in endless arguments.
