Spelling fixes for usr.bin/

Remove the advertising clause from UCB copyrighted files in usr.bin. This

Fix the build on 64-bit hosts. WARNS=6 fails on them.

Inherit WARNS from parent directory.

Submitted by: marius

Directly use memory allocation functions and remove needless casts in
their usage. Also use associated modern types instead of k&r ones.

Change to ANSI-C function definitions.

Build usr.bin/ with WARNS=6 by default.

Also add some missing $FreeBSD$ to keep svn happy.

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.

remove external reference to not (or at least no longer) existing variable 'myname'

Setting a variable to the same value twice doesn't actually make it
more likely to have the right value. Remove superfluous assignments.

This commit eliminates 117 false positive bug reports of the form

Indent the else path, reduce diff against OpenBSD.

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

remove __P

Remove NO_WERRORs and WARNS=n's. To be revisited after GCC3.

WARNS=2 fix, but do not set this im Makefile, because this ill be the
default for src/usr.bin/

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.

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

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.

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.

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.

malloc more space for temp file name

Noticed by: marcel

Feed mkstemp() some more X's to keep it safe.

Make "YYPARSE_PARAM" and "YYPARSE_PARAM_TYPE" C++/ANSI-C clean.

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.

Even better fix for last commit: rename rcsid[] to _yacc-parser_rcsid[]

Don't output rcsid into the output parser. It may have already been

not add $Id$ back into the comment header (as removed from last commit).
