Can we detect libs and automatically exclude symbols from shared
libraries? 

i.e. when linking against libcygwin.a, ALL symbols therein are from a
dll, so -by default- should not be exported.

That would remove the need for many default exclusions, and be closer to
unix behaviour (as I understand it).
