  The following define extracted from MH 6.5 doesn't work with cc's internal
C preprocessor, but does with /usr/lib/cpp:

	#define	grot(x)	case 'x': *dp++ = '\x'; break;

With /usr/lib/cpp, grot(n) expands to:

	case 'n': *dp++ = '\n'; break;

but cc's internal preprocessor produces:

	case 'n': *dp++ = '\x'; break;
