This part of the bug was fixed by a recent commit of mine (and a gdb patch).
With development versions of gfortran and gdb, breaking by "b 2" will break at
line 2 of the Fortran main program.

It's also possible in C with GCC mainline:

(gdb) l
1       int main(void)
2       {
3         int i;
4         i = 1;
5         /* That's all, folks!  */
6       }
(gdb) b 5
Breakpoint 1 at 0x400467: file z.c, line 5.
(gdb) r
Starting program: /home/fxcoudert/devel/debug2/irun/a.out

Breakpoint 1, main () at z.c:6
6       }
