[Boost-users] wregex undefined workaround

Hello, I use freebsd 4.11 & gcc3.3.6 and gcc 3.4.4 with both I don't have std::wstring defined. I only need it fo some internal use. So, I defined: typedef unsigned short uchar16 typedef basic_string<uchar16> string16; and it was enough for me (I don't do iostreams with this string) But, I need regex support for this. As I read in a few mail boost does not create wregex on some platforms with limited support for wchar_t, so I tried to create one the same as I did with string: typedef reg_expression<uchar16, regex_traits<uchar16>, BOOST_DEFAULT_ALLOCATOR(uchar16)> regex16; When I try to use regex16 I get a big load of errors. Did I missed something? Thanks
