One small glitch in the 2009-02-11 signals2 snapshot [1].
When a source file containing only:
#include
is compiled with Visual Studio 2005, it produces:
cl /EHsc /I libraries/include signals2-glitch.cpp
Microsoft (R) 32-bit C/C++ Optimizing Compiler Version 14.00.50727.762

libraries/include\boost/signals2/deconstruct.hpp(510) : error C2874:
using-declaration causes a multiple declaration of
'boost::signals2::detail::deconstruct_access'
libraries/include\boost/signals2/deconstruct.hpp(233) : see
declaration of 'boost::signals2::detail::deconstruct_access'
This is the line in question, near the bottom of
boost/signals2/deconstruct.hpp:
using detail::deconstruct_access;
I'm not sure what the intent is for that line, but removing it solves
that problem without, as far as I'm aware, introducing new problems.
I've attached a patch file.
This line caused me no problems on Mac or Linux. Neither does its removal.
