use extern(Windows) or extern(System)

the compile show the link error:
Error 42: Symbol Undefined _sub at 8

----------------
dll export func name is "sub",
and the dll is 3rd party,i can't change the dll code.

i use "implib.exe /system func.lib func.dll" to create a func.lib.

how can i link correctly?
