How can I request smthg related to the Win run-time ?

[D-Ratiseur]

Hello, I've noticed that an important function (and probably a 
few others) is missing from Windows.d (SetEndOfFile). I'd like to 
put a FR about this but I don't know where-how. Should I register 
here "http://d.puremagic.com/issues/enter_bug.cgi?product=D"; for 
such a stuff (which is not a bug BTW).
Thx.
