New Revision: 66623
URL: http://svn.boost.org/trac/boost/changeset/66623

Log:
Fixes a problem with iterators in Lex identified by M. Gaunard. This prevents
semantics such as "T it; T it2 = ++it;" from compiling. I've added his fix for
this as the semantics in question are clearly legal and the fix implements the
required behavior correctly.
