Hi Peter,
Yes I know how to correct errors :)

1. My sources are designed for IAR for the ATMEL AVR series

2. SDCC messes up pointers, thats my impression too. So Ive dropped that one all together

3. My IAR sources was changed to compile on Keil with around the same effort as you used when going from KEIL to SDCC. Dunno what specific trouble youre having with the IAR.

Well my C comparision is to the end.
We have decided to buy the Keil.

Regards
Henrik Holm
