Hi Luis, i got thes egcs-1.1.2 sources today and rebuilt the cross-compiler and legOS and -- it works now. Thanks a lot for your help !! Could you perhaps give me a starting point to get some understanding of how legOS works internally ? (25 years ago, 16-Nov-99, to lugnet.robotics.rcx.legos)

As I understand it, the patch provides support for interrupts, which, at least from my glance over the code, are necessary only for LNP stuff. (Markus, feel free to correct me on this.) So, it will compile with your "old" cross compiler and provide (...) (25 years ago, 15-Nov-99, to lugnet.robotics.rcx.legos)
