Thanks for your report. This is a known problem; g++ incorrectly
considers the opening '<' as a comparison operator.

You can write this as

      x.template iterate<fun>(f);

instead (which is also standard C++ - if you define f somewhere :-)

I think this also qualifies as a frequently-reported bug.
