get_imp was renamed to class_getMethodImplementation, which is exported from
objc/runtime.h. GNUstep-base uses get_imp to define it's own
class_getMethodImplementation, so get_imp isn't really needed. So either make
the two functions inline, and don't export them, or declare the prototypes. For
the latter I would suggest objc-private/runtime.h (class_getMethodImplementation
is declared in objc/runtime.h).
