It is unlikely IAR will work. eCos uses quite a few gcc extensions.

If you need to make your application smaller i found that -Os has a
big effect compared to -O2 which is the normal eCos default. Also gcc
has been steadily getting better at producing smaller code. So try
using gcc 4.1. If RAM is a problem try tuning your stacks. For some
applications the default stack size is bigger than what is actually
needed. There is code to monitor stack using you can turn on.
