re PR c++/22132 (Wrong code: upcasting a const class pointer to struct the class derives from (C/old-style cast))
PR c++/22132
* call.c (implicit_conversion): Add c_cast_p parameter.
(standard_conversion): Likewise. Allow conversions between
differently-qualified pointer types when performing a C-style
cast.
(add_function_candidate): Adjust callee.
(build_builtin_candidate): Likewise.
(build_user_type_conversion_1): Likewise.
(conditional_conversion): Likewise.
(can_convert_arg): Likewise.
(can_convert_arg_bad): Likewise.
(perform_implicit_conversion): Likewise.
* cp-tree.h (comp_ptr_ttypes_const): Declare.
* typeck.c (comp_ptr_ttypes_const): Give it external linkage.
Return bool.
PR c++/22132
* g++.dg/expr/cast4.C: New test.
