[avr-gcc-list] problems using time.h on freebsd 4.10

[Timothy Smith]

my code example

#include <inttypes.h>
#include <avr/io.h>                                    
#include <time.h>

int main(void)
{     
      DDRA = (1 << 1);  
   time_t blink = time(NULL)+2;
   while (1) {  
           while (blink < time(NULL)) {
               PORTA = 1;
       };
       blink = time(NULL)+2;
       while (blink < time(NULL)) {
           PORTA = 0;
       };
       blink = time(NULL)+2;
      };
}

# avr-gcc -I/usr/include -g -Os -mmcu=atmega32 led.c
/var/tmp//ccJbKrxY.o(.text+0x16): In function `main':
/home/timothy/AVR/led.c:11: undefined reference to `time'
/var/tmp//ccJbKrxY.o(.text+0x2c):/home/timothy/AVR/led.c:13: undefined 
reference to `time'
/var/tmp//ccJbKrxY.o(.text+0x4c):/home/timothy/AVR/led.c:15: undefined 
reference to `time'
/var/tmp//ccJbKrxY.o(.text+0x62):/home/timothy/AVR/led.c:17: undefined 
reference to `time'

if i don't use the -I flag i get

avr-gcc -g -Os -mmcu=atmega32 led.c
led.c:3:18: time.h: No such file or directory
led.c: In function `main':
led.c:8: error: `time_t' undeclared (first use in this function)
led.c:8: error: (Each undeclared identifier is reported only once
led.c:8: error: for each function it appears in.)
led.c:8: error: parse error before "blink"
led.c:10: error: `blink' undeclared (first use in this function)
led.c:10: error: `NULL' undeclared (first use in this function)

however...
ls -l /usr/include/time.h
-r--r--r--  1 root  wheel  5366 May 26  2004 /usr/include/time.h

so time.h is clearly there.

so. obviously there is something funky about time.h and avr-gcc under 
fbsd 4.10. where are my details
