[En-Nut-Discussion] XRAMEND and strtok_r

[Harald Kipp]

Hi Oliver,


>First Problem:

XRAMEND re-appeared in the latest WinAVR.

strtok_r has been added to WinAVR recently. Nut/OS uses
a different, incompatible call

I'll commit these and other fixes to the repository soon. It will
use strtok_r which come with WinAVR.

Thanks for your comments,
