* Makefile.in (BISON): Add comment that when bison is used, it
must include the "-y" option.
* c-exp.y, m2-exp.y (yyrule, yyname, yyss, yyssp, yyvs, yyvsp):
Remove defines to remap non-yacc symbols, thus backing out of
previous recent changes. Standard policy is that non-yacc parser
generators get fixed, rather than adding bug workarounds in gdb
for each new one that pops up. Expand comment to note this.
* c-exp.y, m2-exp.y (YYDEBUG): Revert back to disabled by default.
