[JASS] Why don't the natives work

[Inferior]

Got a question. When I try to implement the three natives:

[jass=natives]native StopWatchCreate takes nothing returns integer
native StopWatchMark takes integer stopwatch returns real
native StopWatchDestroy takes integer stopwatch returns nothing[/code]

JassHelper doesn't give me any error on saving. But when i start the game, although i don't even use them anywhere, my map does not start and I fall back to Wc3 main menue.

Pls HELP.

Where did you find those natives? ;o

Those are for benchmarking. Can be found in the common.j in the japi folder of your JNGP

You need the dll enhancement (not sure how it is called), these natives are not part of wacraft.

EDIT: Link to dll, first link when I googled "StopWatchCreate"
