new warnings from basic_string

[Lars Gullik Bjønnes]

I am not sure if this is known, or if it is something others see as
well.

I recently began getting messages about "control may reach end of
non-void function". Is this known or should I put it in bugzilla?


Code:
#include <boost/lexical_cast.hpp>
#include <string>

std::string convert(int f)
{
        return boost::lexical_cast<std::string>(f);
}


Compiled with:
g++ -W -Wall -O -c -o convert convert.C

Gives:
/opt/gcc-head/lib/gcc/i686-pc-linux-gnu/4.0.0/../../../../include/c++/4.0.0/bits/basic_string.h:
In function #Target boost::lexical_cast(Source) [with Target =
