Hi Julian
With a bit of help on the developers.sun.com Studio fora, I figured out
the cause.
The problem is with the Solaris C++ runtime library. This has to be
backards compatible with older OSes and compilers, so it is built with
basically not a lot of C++ features. So even if the compiler has all of
the features (which Studio 9 has, almost) you can't use them to compile
stuff in the std namespace. So it can't do a partial specialization of
std::iterator_traits.
The workaround is to use the -library=stlport4 option.
A+
