Possibly. Below is a list of symbols from a recent build. The other 
thing is we'd need to turn on flags that make the object suitable for a 
dynamic library (e.g. -fpic). I'm not sure if that has any significant 
impact - probably not or else people would avoid using them far more.

I think we should deal with this. Just Peter's and Steve's responses 
upthread indicate a demand, and I came into this because a customer 
encountered enormous difficulty in doing an out of tree build of a well 
known piece of support software, so this is clearly a pain point. If 
we're not going to do it, we should probably think about adjusting 
people's expectations.
