Unuglified name in __normal_iterator

Whereas uglifying that name cannot hurt, maybe we are conforming, after
all. The snatch is that, as often reminded, the user cannot know which
other standard names are actually pulled in by an #include (besides
those mandated by the relevant Ch. of the standard, of course).
Therefore, the user cannot anticipate whether class reverse_iterator,
which defines a base() member, is pulled in or not. Therefore, cannot
safely use the name base in a preprocessor macro, I think.

Actually, I find this issue rather interesting, albeit academic, of
course. Comments?

Paolo.
