[Boost-users] installing boost_1_47_0

Hi!

Building boost_1_47_0 I with gcc-4.6 -std=c++0x I encountered the errors 
listed below. If I exchange in
libs/signals/src/named_slot_map.cpp

[named_slot_map.cpp:105]
groups.erase(group); [old]
groups.erase( const_group_iterator(group) ); [new]

[named_slot_map.cpp:128]
if (empty(g)) groups.erase(g++); [old]
if (empty(g)) groups.erase( const_group_iterator(g++) );[new]

I am wondering if this is a boost issue or a gcc issue, since the 
compiler should actually be able to convert a map::iterator into a 
map::const_iterator by default, or am I mistaken here?

Regards
Claas

The compiler error in its full beauty:
