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. */
