from the december draft:

3.3.2  Local scope                                 [basic.scope.local]

...

4 Names  declared in the for-init-statement, and in the condition of if,
  while, for, and switch statements are local to the if, while, for,  or
  switch  statement  (including the controlled statement), and shall not
  be redeclared in a subsequent condition of that statement nor  in  the
  outermost  block  (or,  for  the  if  statement,  any of the outermost
  blocks) of the controlled statement; see _stmt.select_.

you can browse it on-line at www.cygnus.com. the reference for
_stmt.select_ above is
