I think it learns it from gdb.  gdb learns if from the debugging symbols in
the executable.  I think there is some interaction with some emacs settings
because I've had situations where I've been unable to insert a breakpoint
in a file by clicking in the left margin, but emacs has been able to bring
me to the right line when gdb stops at a breakpoint inserted the old
fashion way.

If gdb is active and emacs and gdb agree that the file you've opened
is a source file (usually, but not always true in my experience), you can
just left click in the left margin.

I'm responding on-list to this because other people might be able
to give better answers.

Good luck,
