[PATCH 0/1] MR10486: vbscript: Fix error character positions for Exit and Dim statements.
For invalid Exit statements (e.g. Exit Do outside a Do loop), point the error position at the keyword after Exit (Do/For/Function/Property/Sub) instead of at Exit itself, matching Windows. For duplicate Dim declarations, store the identifier location in dim_decl_t and use it as the error position, so the error points at the duplicate name instead of the Dim keyword. -- https://gitlab.winehq.org/wine/wine/-/merge_requests/10486
