EXTERN is a typedef defined to extern on Unix and the DllInport or DllExport facility under Windows. The definition of EXTERN greatly simplifies the creation of DLLs on NT. Very likely TCL is using the same trick. We could rename this macro to something else if we do not receive complaints from users.
