8d03543c79 Have yacc use a prototype for yygrowstack(void) on ANSI compilers. 
This fixes a gcc warning with -Wmissing-prototypes.

87be6e697a 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.

dd079f6ca5 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.

484620e2e4 Make "YYPARSE_PARAM" and "YYPARSE_PARAM_TYPE" C++/ANSI-C clean. 1999-10-28 15:18:05 +00:00
David E. O'Brien
c3584b3b4e 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.

593bbda376 Even better fix for last commit: rename rcsid[] to _yacc-parser_rcsid[] 
(one always gets these ideas just after the commit).

892d5804bb Don't output rcsid into the output parser. It may have already been 
defined in an input file such as src/bin/sh/arith.y.  #if 0 it out.  I did
not add $Id$ back into the comment header (as removed from last commit).

Don't output `sccsid' (set to an anchient UCB Id string) into the parser file.

generate portable code...
* Correctly define yyparse() (ie, K&R vs. C++/ANSI-C)

7c71e88713 Clean up the skeleton code a little. There was a #ifdef to avoid 
stdlib.h unless on C++.  However, we already included it above, so there
was no point using the redundant declarations instead.

86bdf9bc0b #include <stdlib.h> in the C++ case and declare getenv and realloc 
in the C case so that we don't have to depend on stdlib.h being
present.

1130b656e5 Make the long-awaited change from $Id$ to $FreeBSD$ 
This will make a number of things easier in the future, as well as (finally!)
avoiding the Id-smashing problem which has plagued developers for so long.

Boy, I'm glad we're not using sup anymore.  This update would have been
insane otherwise.
