What about this one then? The MinGW linker has an option that allows us
to fudge errors of type "multiple definitions of 'atexit'". With this 
patch tests link against Wine *and* MinGW import libraries, so more tests
compile, link and run.

urlmon is OK now since we still link against Wine imports. Thanks to 
your patch to the dsound test that one is OK too. Only one left failing
is oleaut32. I'm working on getting that one fixed as well. The
natively built test needs libuuid which is specified in $(EXTRALIBS),
but $(EXTRALIBS) is not specified in the linking target for cross 
compiled tests.
