12971	g++ on Windows: warning: converting to non-pointer type from NULL	Fabian Meyer <mail@…>	Andy Tompkins	"The following minimal program ""error.cpp"" generates the warning:


{{{
#include <boost/uuid/random_generator.hpp>

int main()
{
    boost::uuids::uuid id = boost::uuids::random_generator()();
}
}}}

Compiling on Windows (MinGW) with

{{{
g++ -I D:/libraries/boost_1_63_0/ error.cpp
}}}

yields the following message:
