[klibc] get rid of various warnings, errors in io.h

[Jon Smirl]

In 0.97 io.h is wrong in several places.

it should be returning __v, not v.

static __inline__ unsigned char
inb(unsigned short __p)
{
  unsigned char __v;
  asm volatile("inb %1,%0" : "=a" (__v) : "dN" (__p));
  return v;
}


How do I get rid of these warnings?
