Afaik gcc (per 3.4?) nowadays also employs a handwritten RD parser. Afaik
for the same reasons that Barry names.


The parser/lexer for the largely Delphi compatible Open Source Free Pascal
is also handwritten, though not as integrated with (lazarus) intellisense as
Delphi is rumoured to be.


Since the Borland originating Pascal dialects have a limited preprocessor
integrated, effectively it is lexer-preprocessor-parser.


The parser is written in the dialect it parses.
