yes crt0.z was used in my Makefile since i had some startup problem for
the USB Code with crt0i(z) while ago. It seems all to rune fine now with
crt0iz.
So what/where is the prefered location for putting arrays/structs

2. with the code option?
3. or with the #pragma udata ... option?
thx allot for your effort.
