Complain to application maintainers. It is their fault to include
what they are not supposed to include.
Imagine for a second that we make an <asm/io.h> on sparc that
gets included in your program without errors. What makes you think
that inb/outb there may be useful to you, even after ioperm() ?
They easily may happen to be defined as stba/lduba instructions,
or may require port address to be offset.
Programs that resort to direct I/O must carry machine and system
dependent parts with them, including definitions of inb/outb.
If they do not, we cannot help it.
