So I tried this step first (everythin built with the hosts GCC), but
I got the same results! :(

Some info on the new setup:

$ cat /etc/issue
Ubuntu 7.10 \n \l

$ uname -a
Linux vdp-server-1 2.6.22-14-server #1 SMP Tue Feb 12 08:27:05 UTC
2008 i686 GNU/Linux


$ gcc -v
Using built-in specs.

Thread model: posix
gcc version 4.1.3 20070929 (prerelease) (Ubuntu 4.1.2-16ubuntu2)

$ tclsh
% info pa

I'll goto step 1 now.

I have installed the i386-elf toolchain using the ecos-install.tcl script.
Hope this is ok.
