boost/exception_ptr.hpp doesn't compile on mingw gcc 3.4.5

[Ákos Maróy <akos@…>]

when including boost/exception_ptr.hpp, for example via boost/exception.hpp, it fails to compile under mingw / gcc 3.4.5:

$ cat sample.cpp 
#include <boost/exception.hpp>
$ i586-mingw32-g++ -o sample sample.cpp 
In file included from /opt/usr-mingw-41/include/boost/exception/all.hpp:24,

the same code compiles fine when using boost 1.40.0
