Example: 'typedef union { char __mbstate8[128]; } __mbstate_t;'

The only way I've been able to make it work so far is to distinguish between ident's that are types, and non-types, so whenever the grammar processes a typedef statement it turns on a bit, and records the name in a global hash for later. When processing the declaration specifiers for "__mbstate8", it incorrectly considered "__mbstate8" to be a type ident because the typedef bit was ON, but it should have considered "__mbstate8" to be a non-type.

So there's two overlapping issues, (1) how to distinguish between type and non-type _ident_s, and (2) how to get the ident being defined if there is not typedef bit to depend on
