here's a test version of the code, the real code is too big
to show here. This fragment will reproduce the error just like
the big program.

/*--------------------------------------*/
/* 
  inportb is defined in pc.h as: 
  unsigned char inportb(unsigned short port);
*/

#include <pc.h>

void main(void)
{
  /* declare an unsigned char to be the return val */
  unsigned char red;

  /* declare an unsigned short to be the sending parm */
  unsigned short PALETTE_DATA = 0x3c9;

  /* execute it */
  red = inportb(PALETTE_DATA);
}
/*--------------------------------------*/

1. when I run the code through cpp, I can see the pc.h file coming in
without error.

2. when I compile the .c file itself it compiles fine.

3. when I go to link it the message occurs: undefined reference to
'inportb' 

Does this mean that the lib file that contains the "pc.h" functions is
missing or outdated? (it's probably not missing if it's 'libc.a')

answers appreciated,
