AVR-Chat

Hi all,

   I'm using AVR-GCC 4.0.2 with the most recent avr-libc and a target of 
a 90S2313 with this code for a toy "blink the LED" thing.  It builds, 
avrdude downloads it fine, and it doesn't do a blasted thing.  Similar 
code with Bascom/AVR downloaded using avrdude works fine.  Now, this 
isn't the first AVR target I've done with avr-gcc, they all worked, this 
one doesn't.

   Can someone suggest which god I forgot to make a sacrifice to to get 
this to work correctly?  I'm at a loss here.

thanks,
DLC
