Ditto on patience. Close inspection reveals that the config file
studiously avoids accommodating g++ 2.95:

#if defined(__GNUC__) && (__GNUC__ < 3) && \
     ((__GNUC_MINOR__ < 95) || (__GNUC_MINOR__ == 96)) && \
     !defined(__STL_USE_NEW_IOSTREAMS) || \
   defined(__APPLE_CC__)
   // Note that we only set this for GNU C++ prior to 2.95 since the
   // latest patches for that release do contain a minimal <sstream>
   // If you are running a 2.95 release prior to 2.95.3 then this will
need
   // setting, but there is no way to detect that automatically (other
   // than by running the configure script).
   // Also, the unofficial GNU C++ 2.96 included in RedHat 7.1 doesn't
   // have <sstream>.
#  define BOOST_NO_STRINGSTREAM

#endif

In other words, lexical_cast will work if the instructions in the config
file are followed. According to the config file anyone running 2.95 is
in effect on their own. Terje's changes should be applied: any remaining
g++ 2.95 problems would then be down to local config and rather than
lexical_cast.hpp to address.
