1126c5fc83 Let both yacc and lex generate code that passes -Wold-style-definition. 
Both these tools emit code where several functions have no `void'
keyword placed in the arugment list when the function has no arguments.

08fb11c891 Fix a longstanding bug, from Otto Moerbeck: 
if we're reducing a rule that has an empty
right hand side and the yacc stackpointer is pointing at the very
end of the allocated stack, we end up accessing the stack out of
bounds by the implicit $$ = $1 action

d9613ea383 Style improvements recommended by Bruce as a follow up to some 
of the recent WARNS commits. The idea is:

1) FreeBSD id tags should follow vendor tags.
2) Vendor tags should not be compiled (though copyrights probably should).
3) There should be no blank line between including cdefs and __FBSDIF.

8f226dc222 Only use __FBSDID if it is defined. This fixes the 4.4-release (but 
not stable) -> current upgrade path.

589564befb Have yacc use a prototype for yygrowstack(void) on ANSI compilers.

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.

31da8353e2 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.
