Firstly, please don't post MIME base64 encoded mails. It's antisocial and
will only lead to your posts being ignored.

To answer your question, I believe the answer is that in your command-line:

> powerpc-eabi-gcc -msoft-float -mcpu=860 -g --nostdlib -Wl,--gc-sections -Wl,-static -L//C/My_eCos/jwh_test/test6_install/lib -Ttarget.ld -o
//C/My_eCos/jwh_test/test6_install/bin/ecos.elf src/hello.o
src/twothreads.o

It should be -nostdlib with a single hyphen, not --nostdlib, and (just in
case) try placing it after the -Ttarget.ld.
