Bison's -p option fails to work correctly with its -d option.

It changes all occurrences of the given external names, except the
declaration 
	extern YYSTYPE yylval;
in *.tab.h.

For example, if I run bison with
	bison -p foo -d s.y
on this input file:

--- BEGIN INPUT FILE s.y

%token BITE_ME

%%

input: BITE_ME { /* Or don't. */ ; }
--- END INPUT FILE s.y

I get this s.tab.h file:

---- BEGIN OUTPUT FILE s.tab.h
#ifndef YYSTYPE
#define YYSTYPE int
#endif
#define	BITE_ME	258


extern YYSTYPE yylval;
---- END OUTPUT FILE s.tab.h

This is broken because it should be declaring 
	extern YYSTYPE foolval;
instead of
	extern YYSTYPE yylval;
.

I am running bison 1.16 on a Sun 690MP (Sparc) with SunOS 4.1.2.

  The night is pleasing to us because, like memory, it erases idle details.
