Thanks everyone for the help but things are still not working.  It has to
do with the function or the global variable.  If you toggle between the
lines you will see this.  Thank you very much for your help.

  //ledlight = 0

avr-gcc -O0 -Wall -mmcu=at90s2313 -c demo2c.c -o demo1.o
avr-gcc -o demo1.elf demo1.o
avr-objcopy -O ihex demo1.elf demo1.hex

#include <io2313.h>
#include <interrupt.h>
typedef unsigned char BYTE;

void led1(void);
BYTE ledlight;

void led1(void){
  ledlight = 0;// = 0x00;

int main(void) {
  outp(255, DDRB);           // port B all outputs
  outp(255, PORTB);          // turn all leds off

  //ledlight = 0;

    outp(ledlight, PORTB);        // turn led on
