Just did that.

I'm using VisualAge C++ 3 but maybe my experience will be useful.

Same.

They are functionally equivalent, at least here. EXPENTRY & APIENTRY
both are defined as '_System'. MRESULT should be a ULONG also.

Possibly. _Packed is an old keyword equivalent to

#pragma pack(1)

or something similiar for Borland.
