9f5b04e925 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.

bc505f7742 Only use __FBSDID if it is defined. This fixes the 4.4-release (but 
not stable) -> current upgrade path.

c613a5e7dc 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.

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.

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

fae4b464e3 Use mkstemp rather than mktemp for yacc's temp files. This change was made
