Hi, out of curiousity, could you try editing the .c file and adding
#define _start start
#define _end end
after the header file includes and before the
extern void _start,_end;
declarations then try recompiling it? then if that doesn't work, try
#define _start __start
#define _end __end
The command you need to run to recompile the .c file will be embedded in
the file near the top of it, or the utils/recomp.prl script will pull it
out and recompile a .c generated by jhc. (useful when debugging the
