Re: [boost] [uuid] - boost/algorithm/string.hpp - error no matching function for call to 'find(wchar_t [16], wchar_t* const&, wchar_t&)'

Hi,

uuid is using std::find without qualification and so it conflicts with
boost::find declared in the string_algo.

Looking through the uuid.hpp code, there are lots of 'using namespace'
directives. Althoug they are only local, they could cause problems,
especialy in the scope of boost.

Regards,
Pavol.
