This code does nothing; SDCC is correct to generate an empty function
(this code first dereferences ucP (and does nothing with the result), then
increments the pointer (since the pointer value is never used again, this
is also a no-op)).

This does what I think you want, and appears to generate correct code:

void foo(char *cp)
{
    (*cp)++;
}

        Peace,
