This usually works even on cranky compilers:

unsigned char x = 0xC2; printf("this is the problem %02X\n", (unsigned int)x);

But we agree that the conversion "unsigned char" ==> "unsigned int" must result in exactly the same result, no matter if done implicitely or by explicit cast?

If this doesn't work it means that the toolchain is broken and/or misconfigured. Maybe there is no valid prototype for printf() active, etc., but this should be visible when compiling with warnings turned on.
