What happened next:
-) mknbi-linux suddenly has the same problems. These were "solved"
   after inserting a 'printf("argc = %d\n", arc);' as the first executed
   line in the main() function.
-) I inserted some printf's in the main() function of makerom/main.c, which
   made it work "longer" (if you count the syscalls). After inserting some
   much longer strings in the output I get now a "image.rom" file (which
   seems to be too short wuth 2512 bytes).
-) Inserting a few more bytes made makerom work.

Hmm, is this a gcc-2.8.1 bug ?
