Allow redefinition of enum types and enumerators. Diagnose
nested redefinitions including redefinitions in the enum
specifier for enum types with fixed underlying type.
gcc/c:
* c-tree.h (c_parser_enum_specifier): Add parameter.
* c-decl.cc (start_enum): Allow redefinition.

-Wincompatible-pointer-types is now an error by default. OK with that
changed as needed (you may also need such a chan
(only tests were changed)
