Hi,
ÂThe problem here is that same_type_p will return false if the type
is a volatile bool when we are checking if the type is a bool type.
This fixes the problem by just checking the type's code as the only
bool types are BOOLEAN_TYPE. and BOOLEAN_TYPEs are always considered
the bool type in C++.

OK? Bootstrapped and tested on x86_64-linux-gnu with no regressions.

Thanks,
Andrew Pinski

ChangeLog:

* typeck.c (cp_build_unary_op): Check TREE_CODE for bools instead of
using same_type_p.

* g++.dg/expr/bool3.C: New testcase.
* g++.dg/expr/bool4.C: New testcase.
