Unfortunately I found a new problem in
Boost.Optional. I get weird compile 
errors in one project, both with MSVC12 
and MSVC14:
error C3083: ' ?? A0x6071e18f': the
symbol to the left of a '::' must be a 
type
for a line declaring a member function
with a boost::optional parameter 
with a default value of boost::none.
BOOST_OPTIONAL_USE_OLD_DEFINITION_OF_NONE
...
fixes the problem.
I've finally been able to reproduce the 
problem. It occurs only if 
<boost/optional.hpp> is in the precompiled 
headers.
