7d2463e9d1 Increase the table size by an order of magnitude. 
The previous version was too small and YACC core dumped on the during the
hybrid-7 build.

589564befb Have yacc use a prototype for yygrowstack(void) on ANSI compilers. 
This fixes a gcc warning with -Wmissing-prototypes.

5240cf8e35 Fix breakage introduced in rev.1.7. yystacksize and yysslim are global and 
should be prefixed by YYPREFIX as well.

Only relevant if -p <yyprefix> is used. Used in cases where multiple parsers
are used in executable.

668e3ec014 Fixed breakage of K&R support in rev.1.26. yyparse() was defined as 
`int yyparse(;) ; { ... }' in K&R mode.  Getting rid of the second
unwanted semicolon in this made the ifdef tangle more tangled than
before.  Fixed a backwards comment in the tangle.

6b3da1fe21 Fixed breakage of K&R support in rev.1.8 of output.c: don't generate 
#elif.  Cleaned up rev.1.8 a bit more: generate the #include of
<stdio.h> closer to the code that needs it.

811b0ef57d Make "YYPARSE_PARAM" and "YYPARSE_PARAM_TYPE" C++/ANSI-C clean. 1999-10-28 15:18:05 +00:00

3a2839fec9 Allow a user specified parameter to 'yyparse()', in a manner similar to 
that used by bison.  The names are consistent with the bison implementation
but this one also allows the type of the parameter to be specified.

For a desired prototype of:

	int yyparse __P((struct yyresult *));

and compile like this:

	yacc -dv grammar.y
	cc -c -DYYPARSE_PARAM_TYPE="struct yyresult *" \
	      -DYYPARSE_PARAM="parm" y.tab.c

and use like this:

	${
	#include "usrtypes.h"
	#include "usrproto.h"
	}$

	%token NUMBER

	%%

	goal : NUMBER
		{
		parm->value = yylval;
		} ;

If YYPARSE_PARAM_TYPE isn't specified then "void *" is the default type.
If YYPARSE_PARAM is not specified then the generated code behaves exactly
as traditional byacc.

stdlib.h unless on C++.  However, we already included it above, so there
was no point using the redundant declarations instead.
