--add-stdcall-alias equivalent for Visual-C++ ?

[Jim Kleckner]

An off-topic request:

The --add-stdcall-alias argument to ld exports symbols as both 
"decorated" (with leading _ and trailing @nn) and "undecorated".

Anyone know of the easiest way to get VC++ to do this?
Yes, a manual exports .def file can be created (or semi-automated).

But it is so nice that ld does this which is needed for Excel or other 
DLL-consuming Windoze programs.
