Thanks, but can you explain the reasons for these changes?  They look
strange to me.  E.g., why do you care which symbol is #undef'ed here:

>  /* Define to read input using SIGIO. */
> -#undef INTERRUPT_INPUT
> +#undef INTERRUPT_INPUT0

Or why do you need to avoid using enum here:

This sounds like a kludgey solution fopr some problem, but what is the
problem?

Are these all the changes you need, or just a sample?
