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