As it turns out, nearly all compilers that *don't* support the signed
keyword have chars signed by default. So, use 'signed char' whenever
your char must be signed. For compilers that don't support signed,

	#if ARCHAIC_C
	printf("Complain to your vendor.\n");
	#define signed
	#endif

Interestingly, all current C compilers on MS-DOS that I'm familiar with
support 'signed'.
