if I try both of your suggestions it works though I also tried it with 
another function name (like "void foo(void){}) and it still works, so 
that name has no special meaning. I take it that because there is no 
crt0.S, no "main"-function is required. Still then I don't understand 
why using "main" produces the "EH_FRAME"-error.

Basically I feel like I need to do a lot of reading, but the problem is, 
I don't really know where to look. :-(
Will see if the GCC-manual can give me some insight.
