references.
Actually, depending on preprocessor conditions that we don't want
to mirror here (as they may change depending on readline versions),
readline may define these globals as well, relying on the linker
merging them if needed (-fcommon). That doesn't work with
-fno-common or C++, so instead we define the symbols as weak.
Don't do this on Windows though, as MinGW gcc 3.4.2 doesn't support
weak (later versions, e.g., 4.8, do support it). Given this stub
file originally was Windows only, and we only needed this when we
made it work on other hosts, it should be OK. */
