I don't know about the specifics, but I'd definitely prefer the same 
semantics (at least from the "end" user's point of view).

Linking the DLL isn't different from linking an EXE in this case. You can't 
link the DLL without having the function definition available at link time.

You could solve this using callbacks, but as a DLL can't define main anyway, 
what are you actually trying to do? Would it be an alternative to have 
Boost.Test as a DLL, minus the definition of main, which could be provided 
by e.g. an object (or a static library, but IIRC there's a problem with 
having main's defined in static libraries on certain compilers/platforms - 
the linker doesn't recognize there's a main at all)?

Just thinking out loud.
