PF_ATYPE is the important part of PF_LOOKFORTYPENAME, the macro that
|
|
tells the lexer whether or not it is valid to return an L_TYPENAME
|
|
token. It should be cleared after a valid type is read (int, another
|
|
typedefed name, struct x, etc) and reset after an identifier is assigned
|
|
to that type.
