I am using gcc-3.0.4, target arm-ecos-elf. This works
quite well. gcc-3.1 does not compile all those functions
that use weak aliases, such as memcpy(). I also encountered
problems building binutils with my native gcc-3.1, it miscompiles
ld.

Using gcc-3.0.4 requires one additional step when creating
an ecos configuration. You have to edit the generated target.ld
and remove the reference to libsupc++.a. This is a library of
small C++ support functions that gcc uses. I guess it would be
relatively easy to make an ecos package providing this library,
which would eliminate the need for this additional step.
