This function does seem to have gone missing from the BSD network stack.
However, it does bring up a point - this function is really designed for
creating a socket/pipe which can be shared between two processes.  Since
eCos is not process oriented, why would you want to use it?

Also, why are you using a modified "net" template?  There are much 
better ways to adapt/tune your configuration than changing common
files like the template.
