- 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.

// rationale for allocating MemFun_t dynamically:
|
|
// need to store class pointer, function, and argument for each registered
|
|
// function; single static storage isn't possible. we don't want to break
|
|
// C compat in the Loader.h interface, so we can't have it take care of this.
|
|
// that leaves dynamic alloc or reserving some static storage freed when
|
|
// load registration begins. the former is slower and requires checking
|
|
// the thunked function's return value (because we mustn't free MemFun_t
|
|
// if the function times out), but is simpler.
