* NEW: Bytecode version has been increased, and so all projects must be recompiled. [INTERPRETER] * OPT: Objects that do not raise events do not allocate the event management structure anymore. That save four pointers by object. * NEW: Structure management is done, and embedded (static) structures are handled too. * BUG: Static array management was fixed. * NEW: All functions synonymous whose name ends with a question mark have been removed. [COMPILER] * OPT: Some optimization again. * BUG: EXTERN declarations compile again. [GB.DB.SQLITE2] * BUG: Fix a misuse of GB.NewString(). git-svn-id: svn://localhost/gambas/trunk@2970 867c0c6c-44f3-4631-809d-bfa615b0a4ec
