23**
24** Yacc/Bison grammar for extended ANSI C used by LCLint.
25**
26** original grammar by Nate Osgood ---
27** hacrat@catfish.lcs.mit.edu Mon Jun 14 13:06:32 1993
28**
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
34**
35** production names are cryptic, so more productions fit on one line
36**
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
