[PATCH v2 1/2] widl: Do not generate C++ enum typedefs in WinRT mode.
MIDL generates enum typedefs without a prior type declaration, as well as using explicit enum underlying type specifier. None of this is supported in MinGW. Signed-off-by: Rémi Bernon <rbernon(a)codeweavers.com> --- First patch should fix the C++ breakage introduced with 2a7940c97d4e6c, and second patch should fix pre-existing C++ code breakage when using types from different namespaces.

Declaration type names prefer unqualified names whereas reference type names prefer fully qualified names. This makes C++ code use fully qualified names when referencing a type, fixing cases where types from other namespaces are used. It also allows to skip the enum / struct / union type prefix in WinRT C++ code.
