MS semantics for dllimport for ordinary file scope functions, is that if a
declaration with dllimport attribute is followed by a decl without, the prior
dllimport is overriden.  Hence, the warning that Stephen shows for df3.cc  in
comment #3 may make some sense, but I do not have a MS compiler handy to see
what MS says for the friend case.  The warning does not make sense, if the 
dllimport attribute is actually honoured (as it should be) in original
testcase.
