Link to static library from DSO without exporting symbols?

[Boris]

Is it possible to link to a static library from a DSO without exporting the 
symbols in the DSO again? I have a DSO here for example which makes use of 
the Expat XML parser. When I link the Expat XML parser though the DSO 
exports all symbols of the Expat XML parser. Is there any option to tell g++ 
or the linker not to do this? From what I understand the rule of thumb is to 
make the list of exported symbols as short as possible?
