[PATCH v6 0/1] MR10404: Draft: vbscript: Reject arguments on Class_Initialize and Class_Terminate.
Windows returns error 1053 when Class_Initialize or Class_Terminate are declared with arguments. Add the same check in compile_class() and store source location in function_decl_t for accurate error reporting. -- v6: vbscript: Reject arguments on Class_Initialize and Class_Terminate. https://gitlab.winehq.org/wine/wine/-/merge_requests/10404
From: Francis De Brabandere <francisdb@gmail.com> Windows returns error 1053 when Class_Initialize or Class_Terminate are declared with arguments.
