There's a much easier way than that.  Type the code in and see what
happens.  My manager uses IAR and I use avr-gcc.  Most of the
differences that I see between those two compilers result in compile
time errors, which is a good sign that "Hey, I've found a difference!"
A glance over the avr-libc FAQ or a quick Google will then hopefully
tell you how to translate the code.  If not, there's always the list.

On a related note, it might be useful to have a "(Codevision|IAR)
Programmer's Guide to avr-gcc" or a "(Codevision|IAR) to avr-gcc Porting
Guide".  I don't think such documents exist, do they?
