[boost] [HEAD] lexical_cast<int8_t>("127") bug?

Hi Everyone,

I've recently tried the following (inlined test) which isolates the
problem I've encountered with boost::lexical_cast<int8_t>:

#include <iostream>
#include <boost/lexical_cast.hpp>

int main(int argc, char * argv[]) {
    int8_t value;
    try {
        value = boost::lexical_cast<int8_t>("127");
    } catch (std::exception & e) {
        std::cerr << e.what() << '\n';
    }
    return 0;
};

This is compiled with gcc 4.1.2 on Linux. Any idea why 127 wouldn't
fit into an 8-bit signed integer? The defined range for signed 8 bit
integers should be -127..+127 right?

Am I missing something?

Insights and pointers would be most appreciated.
