This was posted for Jim Roskind (jar@ileaf.com) because his news
posting facilities were not delivering outgoings messages consistently:

I (Jim) have written a pair of YACC able grammars for C++ and C, and
posted them to the net (or at least tried).  The posting consists of 4
items, including the 2 grammars, a paper on the ambiguities in the C++
syntax, and an introductory letter.  Since these items total 160K of
text, I am reluctant to "re-post" until I am sure that the first
posting has fallen into the bit bucket.  In the mean time, Doug Lea
and Doug Schmidt have graciously offer to provide anonymous ftp
sites for these 4 files.

Note that the grammars are VERY clean, and make no use of the YACC
%prec and %assoc constructs.  The C++ grammar also supports old style
function definitions (a feat that no other parser I am aware of
offers).  The associated paper identifies a number of fundamental
ambiguities in C++ that have not received public exposure (read: they
represent buggy areas of all existing compilers and translators that I
know of).  The grammars have copyrights that should allow for their
use in any commercial or non-commercial releases, and there are no
fees involved with their use (nor are these items copylefted).

The files can be obtained from:

ics.uci.edu (128.195.1.1) in the ftp/pub directory as
c++-grammar.1.0.tar.Z.

c++gram.tar.Z, holding them all available for anonymous ftp at
mach1.npac.syr.edu:~ftp/pub/C++ and labrea.stanford.edu:~ftp/pub
