           gcc 3.x (3.3pre, at least) swallows it nicely.

           The problem here is the 'typename' part: without that gcc
           2.95.3 compiles it fine. gcc 3, however, warns that
           "implicite typenames are deprecated", and this kills my
           builds (i always use -Werror :/).
