24 ** Yacc/Bison grammar for extended ANSI C used by LCLint.
26 ** original grammar by Nate Osgood ---
27 ** hacrat@catfish.lcs.mit.edu Mon Jun 14 13:06:32 1993
29 ** changes for LCLint --- handle typedef names correctly
30 ** fix struct/union parsing bug (empty struct is accepted)
31 ** add productions to handle macros --- require
32 ** error correction --- main source of conflicts in grammar.
33 ** need to process initializations sequentially, L->R
35 ** production names are cryptic, so more productions fit on one line
37 ** conflicts: 87 shift/reduce, 18 reduce/reduce
38 ** most of these are due to handling macros
39 ** a few are due to handling type expressions
