It worked! :)

I did a fresh start, i.e install ecos with i386-elf binaries.

This is what I did (on my Ubuntu 9.04):

$ mkdir linux-synth
$ cd linux-synth
$ ecosconfig new linux
$ ecosconfig add lwip_eth
$ ecosconfig add libc_stdio
$ ecosconfig tree

edit ecos.ecc
change CYGBLD_GLOBAL_CFLAGS, append -fno-stack-protector

$ make
$ sed -i 's/ libgcc_eh.a//' install/lib/target.ld
$ make tests
$ ./install/tests/language/c/libc/stdio/v3_0/tests/stdiooutput

NOTE: I did not have to give the "-io" option.

Sergei, John, thanks a lot for your help.
