Thanks for the reply. But it still doesn't work.

interface ISomeComInterface : IUnknown
{
	void funcWithManyParams(/*10 params*/);

	extern(/*insert whatever linkage here*/)
	void funcWrapperWithLessParams(/*3 params*/)
	{
		funcWithManyParams(/*fill in some default params*/);
	}
	//this func is inlined in the MS SDK header
}

DMD complains that the function body of funcWrapperWithLessParams isn't 
abstract.
