It looks like we could use a FAQ file on the subject of typedef
identifiers in C parsers. Folks are coming to the discussion late, and
starting the discussion over from square one. One well-meaning fellow
recently said that having the lexer look at the symbol-table violates
"engineering principles" and thus should not be done. He has obviously
never tried to implement the C grammar with a standard one-token-lookahead
parser generator, or he would know that it is not quite that simple.


So how about a FAQ? Volunteers anyone?

happy to add it to the archives. Otherwise I'm declaring this topic closed.
