* gdb.base/callfuncs.exp: Make "print add" messages unique. * gdb.base/ending-run.exp: Put spaces around "breakpoint" to stop matching directories by the name breakpoint. * gdb.base/pointers.exp: Make "ptype pppC" message consistent. Make "continue to marker1" consistent. * gdb.base/call-rt-st.exp: Make "finish out from loop_count" message consistent. * lib/gdb.exp: Put "the program is no longer running", and "the program exited" in parenthesis. * lib/mi-support.exp: Ditto.
