foo.y:

%{

#define IN_BISON

#include "foo.h"

namespace foo
{

// some declarations, including yyerror

%}

// grammar and everything

%%
}

foo.h:

#include <...>

namespace foo
{

// various other declarations

#ifndef IN_BISON
int yyparse (...);
#endif

}

Not sure if it's supposed to work like this, but currently it does. :)
