+/* ??? This interface isn't intended to be specific to any particular kind
+ of remote (hardware, simulator, whatever). However, at the present
+ time it is only used by the simulators. At some point this should be
+ an entity onto itself. For example, it's wrong that the definitions of the
+ functions host_to_target_errno, target_to_host_open live in the simulator
+ sources. It would also be wrong for such functions to live in gdb
+ sources. Until such time perhaps it would be best to avoid adding
+ prototypes of functions (and thus expanding the definition of the
+ interface). */
