Doing that would effectively declare all code inline, possibly causing massive 
code bloat and compile time increase. I don't think its a good idea.

Attached is a file. Copy it to the boost/signals folder and include it from 
exactly one translation unit of your program. All it does is make an 
on-demand compiled, statically linked library.

BTW: I have the same for Boost.Thread here, though it requires a patch to one 
file, and intend to attempt the same for other libraries requiring linking, 
too.
