Hi,


        No matter how many shots at it, I havent been
        able to get bison/yacc to parse the C++ grammar
        specified in the reference manual.


        Factoring and other smart tricks leave the grammar
        as much different from the original grammar
        and no matter what, shift/reduce and reduce/reduce
        conflicts run galore.


        Is there any trick that I may be missing?


        How do I get the grammar in the manual
        not to change much as well as pass under
        bison/yacc?


Sincerely,
Partha Sarathi Panda
[C++ is context sensitive. You can't parse it using a yacc parser
unless you do some serious external hackery to look ahead and feed
hints back to the parser. This has been discussed at length in the
past, so look at the archives. -John]
