Another alternative is to grab the line number when the breakpoint is 
set, and compare against that.  It does mean that gdb could have the 
line number woefully incorrect, but at least gdb has to be consistently 
incorrect.  e.g. something like

    send_gdb "break marker4\n"
    gdb_expect {
      -re "Breakpoint.*at.* file .*$srcfile, line ($decimal).*" {
        set marker4_lineno $expect_out(1,string)
      }
[...]
    }

Or drop the PROTOTYPES-is-undefined case altogether.  I have no idea if 
there are cross-compilers in use that don't support prototypes, though..
