#include <stdio.h>

struct HighLowBits {
     unsigned int highbit:  1;
     unsigned int lowbits:  7;
};

I think this may do the trick. I'll have to verify it on a PC.

On a 486 based machine running SVR4, compiling with both the native cc and with gcc, the result is:

        This is a LittleEndian machine
        Byte with highbit set has value 1
