for MS dll's, you can use 'impdef' do get a list of the entries. Note
that these do not have a '@xx' suffix, where 'xx' is the size of the
parameters on the stack. You can edit this file against the header. The
rule of thumb seems to be, 4 bytes per parameter, so Foo() would be  
Foo AT 0,  Foo(int, int, char*) Foo AT 12, etc. I think Anders Norlander has a
tool for this fixup on the def files, but I haven't used it.

Then you can say,

dlltool -D foo.dll -d foo.def -llibfoo.a -k

NB: the '-k' kills the export of the decorated name. Gcc needs to see
the *@xx form, while the dll must be called with the undecorated name.

afaik, the instructions on the web site are for linking against a dll
created by gcc, not a MS dll. The above seems to work for me, but if
there is an easier or more correct procedure, I'd like to see it.
