RTTI defaults to "On" since msvc++ 8.0 ...
...and yes with rtti on boost::function<> still produced a larger binary...
msvc++ tr1 function<> did add one or two rtti records more (if rtti is left 
enabled) but, as i elaborated in my first post, it turns out this is actually a 
less important issue (relatively speaking)...maybe it would become more 
important for projects/binaries with a large number of different function<> 
instantiations (comparing to the relatively few i tested with) because the much 
more complex/'bloated' boost::function<> 'throw bad_function_call' machinery 
(as compared to the same 'machinery' in mscv++ tr1 function<>) would become 
less important (as atleast some parts of it are 'allocated' only once/not part 
of the template)...but the template bloat issues i outlined in my first post 
would still prevail significantly (over a larger number of rtti records, which 
can be turned off if you do not use rtti otherwise)...

ps. i don't know, is a topic name change in order? like a request for a mini 
review or something...
