    I need to write a driver using inb() and outb().
    I am struggling with compiling a simple test program
    to test these fuctions.
    (1.) If I use gcc -o -DMODULE -D__KERNEL__ -c myfile.c
         I do not understand how to use the resulting file
         created -DMODULE.
    (2.) If I use gcc -o tst tst.c the following fail appears.
         undefined reference to __inbc
         undefeined reference to __inb
What I expected was a executable program to run from the command line. Thanks Terry M. tmoore@solbrn.dseg.ti.com
