ok, but then if the application also has a need to access the metric data
(like gmond) then we will end up including gm_protocol.h twice, and that
will lead to redefined symbols (that headers is generated by rpcgen and
might not have protection against multiple inclusion)

but since they are most likely to use at least the debug and error message
prototypes it shouldn't be a problem to include it.
