Hi,
In reponse to the thread begun here:
http://lists.gnu.org/archive/html/help-bison/2007-10/msg00049.html
I've attached a proposed patch for the C parser skeleton (yacc.c) that
improves usability with C++ compilation (regarding malloc prototype), even
though it is not officially supported. Please consider this patch, or let
me know why it cannot be accepted. Thanks.
