[boost] [xpressive] unused variable warning

From: Christoph Duelli (duelli_at_[hidden])
Date: 2008-05-30 04:44:35

in end_impl.hpp
(at the very bottom)

     static type
     call(Sequence& t)
     {
        return type();
     }

The unused t causes a hideous amount of warnings (gcc4.1.2).
Took me 15 mins trying to find my error til I discovered that those pages of
output were not really an error message but 'only' a (very annoying)
warning.

Please fix this. Thank you.

Best regards
Christoph
