[please disregard if this is the second copy, i'm having problems with mail]

I did a quick grep and I cant find char_traits, but if you replace that by
string_char_traits
it compiles nicely. this is probably one of those cases where g++ is not
quite standard; I had some issues with strstream as well. eagerly waiting
for 3.0 :-))
