[PATCH] Cast Name to a ULONG before checking its valid

[Owen Smith <owen.smith@xxxxxxxxxx>]

MSVC treats all unscoped enums as an int, so the signed value needs
casting to an unsigned before only checking against the maximum enum
value.
Fixes
warning C33010:  Unchecked lower bound for enum Name used as index
