Hi everyone, I am finally getting back to (trying to) contributing some 
of my personal projects to Boost.
For two of those, Err (https://github.com/psiha/err) and especially 
Functonoid (a C++11 generalization and rewrite of my previous 
Boost.Function related work) I need some lower level codegen and/or 
optimiser control functionality (i.e. portable macros wrapping toolset 
specific attributes and pragmas) that I've added to my personal fork of 
Boost.Config and which I've now submitted in the subject PR 
(https://github.com/boostorg/config/pull/82).

I don't expect this PR to be accepted as is/'just like that' so I'm 
opening this thread where we can discuss which of those changes/macros 
are welcome, which need more work and which, for some reason, should not 
be part of Boost.Config (and which, in turn then, I have to move to some 
'internal implementation headers' in libraries that will need them).

To avoid 'spamming' (and save time;) I'll skip the explanation of the 
individual macros as I expect them to mostly be self-explanatory (if not 
from their name then from the minimal Boost.Config documentation 
additions that are part of th PR).

ps. I'll be on the (off) road for the next three weeks so I don't know 
when I'll be able to respond until I get back...
