Not directly.  You can create an implib for the dll, and then link 
against the implib.  Use pexports to create a .def file for the dll, 
then use dlltool to generate an implib from the .def+.dll.  pexports is 
available from http://infoservice.lg.ua/~paul/devel/binutils.html. 
Dlltool is part of binutils.

Obviously, I haven't done all your work for you -- you're going to have 
to read the manuals to figure out how to do the above tasks...

Doesn't MSVC ship .lib files (VC-style import libs) for the system 
.dll's and ACTUALLY links against those?)  I'm not convinced that MSVC 
*can* link directly to a stripped dll (or even an unstripped dll, for 
that matter) without using an import lib.  gcc's ability to link 
directly to a dll (unstripped) without using an implib was fairly 
innovative, I thought...
