1b8ae690 29** Yacc/Bison grammar for extended ANSI C used by Splint.
885824d3 30**
31** original grammar by Nate Osgood ---
32** hacrat@catfish.lcs.mit.edu Mon Jun 14 13:06:32 1993
33**
1b8ae690 34** changes for Splint --- handle typedef names correctly
885824d3 35** fix struct/union parsing bug (empty struct is accepted)
36** add productions to handle macros --- require
37** error correction --- main source of conflicts in grammar.
38** need to process initializations sequentially, L->R
39**
40** production names are cryptic, so more productions fit on one line
41**
42** conflicts: 87 shift/reduce, 18 reduce/reduce
43** most of these are due to handling macros
44** a few are due to handling type expressions
