4495,Including dynamic_bitset while using BGL's boost::dynamic_properties forces operator>> into std namespace,Thomas Krennwallner <tkren@…>,Gennaro Prota,"Including {{{dynamic_bitset.hpp}}} (without using it) breaks previously working BGL code, which uses {{{boost::dynamic_properties}}}. We get the following error:

{{{/opt/local/include/boost/lexical_cast.hpp:785: error: no match for 'operator>>' in 'stream >> output'}}}

Wrapping my {{{operator>>}}} into {{{namespace std}}} fixes the compiler error.

I've created a rather ""minimal"" example which should confirm this (simply run {{{g++ XXX.cpp}}}):

 * {{{xxx.cpp}}}: this is the version without dynamic_bitset and compiles
 * {{{yyy.cpp}}}: a variant of {{{xxx.cpp}}} which includes dynamic_bitset; gives above compiler error
 * {{{zzz.cpp}}}: this is a variant of {{{yyy.cpp}}} which compiles again

The problem can be reproduced in Boost 1.43.0 and in Boost trunk.",Bugs,closed,Boost 1.44.0,dynamic_bitset,Boost 1.43.0,Problem,invalid,,ghionna@… dao@…
