Yes, I see the same with my old snapshot of GDB 7.0: I cannot step
into the 'print' function, unless I use "stepi".  then I see this:

  0x00001611        16           bytes = print(message);
  (gdb) si
  0x000015ac in print (message=0x8f950 "qwertz")
  (gdb) n
  Single stepping until exit from function print,
  which has no line number information.
  This is the message:  "qwertz"
  main () at a.c:17
  17           return bytes;

So the problem is that GCC doesn't produce line number information for
GDB to use in this case.

Anyway, please try to debug larger programs.  If that works, it's good
enough.

Thanks.
