[Bug] Enum name throws when LongPtr

[SSlinky]

Describe the bug
Enums require an name that isn't a reserved word or type. What counts as a reserved word or type depends on the version.

To Reproduce
Steps to reproduce the behavior:

#If VBA7 = 0 then
  Enum LongPtr
    [_]
  End Enum
#End if

Code (if relevant)

enumDeclaration: ENUM wsc untypedName endOfStatement+ enumMemberList endOfStatement+ END wsc ENUM ;

Expected behavior
LongPtr should be a valid enum name. The parser shouldn't care it's a reserved word or type.
