+   Actually, depending on preprocessor conditions that we don't want

+   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.  */
