- add convenience macros for config_db(CFG_GET_SYS_VAL) - VFSUtil::EnumDirEnts now uses flags instead of bool recursive - UNUSED() for params, UNUSED2 (<- need better name) for variables - config.h defines must be tested with #if (always defined) -> allows detecting misspellings thanks to compiler warnings - replace debug_assert(0) with debug_warn (its sole purpose) - replace ScriptingHost::ValueToInt et al with ToPrimitive - use nommgr.h to disable both mmgr and VC debug heap This was SVN commit r2585.
