[boost] [minmax] failure in GCC 3.4.1

GCC 3.4.1 complains with this absolutely clear run-time message
(http://tinyurl.com/42bey):

error: attempt to copy-construct an iterator from a singular iterator

I've inspected the code of minmax_element_test.cpp and think the
problem lies in lines 106-107:

  CIterator min, max;
  RCIterator rfirst(last), rlast(first), rmin(min), rmax(max);

where rmin and rmax are copy-constructed from min,max, which are
singular.
Anyone sees a problem in fixing this? (Please find diff below.) I
don't have GCC 3.4.1 available, so I can only guess this will clear the
problem away.
