Currently I get two warning when compiling regex with gcc-3.2.3 on Tru64 and I think the warnings are justified. The first one is in "basic_regex_parser.hpp" at line 1284 where it complains about a signed/unsigned mismatch. The code in question is "(i > (std::numeric_limits<charT>::max)())" where i is an int and charT=wchar_t is unsigned. Isn't there a conversion missing here? The second one is in "cpp_regex_traits.hpp" at line 970. There is a "BOOST_USE_FACET(std::numpunct<char>, ...)" which I think should read "BOOST_USE_FACET(std::numpunct<charT>, ...)". Markus
