 I'm getting an "Overloading ambiguity error" when building
 libs/signals/src/named_slot_map.cpp on or around lines 105 & 128 on the
 calls to `groups.erase`.

 This may be related to an issue [http://www.open-

 std.org/jtc1/sc22/wg21/docs/lwg-unresolved.html talked about here], but
 that issue seems to indicate the problem would only exist in C++11.

 The error goes away with the following minor edits:

 {{{
 -105:     groups.erase((const_group_iterator) group);
 +105:     groups.erase(*(const_group_iterator) group);
 -128:     if (empty(g)) groups.erase((const_group_iterator) g++);
 +128:     if (empty(g)) groups.erase(*(const_group_iterator) g++);
 }}}

 I'm doing this work on an airgapped network, and the error is rather
 verbose ... but I'll give a shorted version of the error:

 {{{
 "libs/signals/src/named_slot_map.cpp", line 105: Overloading ambiguity
 between "std::map<A>::erase( __rw::__rw_tree_iter<B> )" and
 "std::map<A>::erase(const  boost::signals::detail::stored_group&)".
 "libs/signals/src/named_slot_map.cpp", line 128: Overloading ambiguity
 between "std::map<A>::erase( __rw::__rw_tree_iter<B> )" and
 "std::map<A>::erase(const  boost::signals::detail::stored_group&)".
 }}}
