I had the same problems when I tried to compile iconx as ELF
binary. But iconc compiled without problems and works. I would be very
grateful for a solution, too.
The problems occurred with the configuration for i486_linux
(i386_linux didn't work either, but I don't remember why). I guess
(but I am not a C- or Assembler-programmer) that the problem has to do
with the Assembler code in rswitch.s.

Here is my setup:
   486DX66, 16MB RAM
   Slackware 3.0 ELF
   gcc 2.7.0

Here are the error messages:
