Gary,

Thanks for the prompt answer. I was speaking more in the context of linking
and compiling the image.

I see that a call to enable interrupts is not necessary when threads are
initialized.

I also see the cyg_interrupt_enable in the map file, which jumps to the
hal_interrupts_enable( from vector.S but not in the map file) code in the
application.

Thanks and Regards,
Aaron Case
