Actually we'd rather not generate toolchains that way. By generating 
toolchains with newlib, it's possible to run "make check" on the compiler 
with the built-in simulators without requiring eCos ports for all of them.

Oh that's certainly possible, and indeed should probably work. The 2.95 
instructions didn't require newlib either for example.

We wouldn't want to use non-standard setups ourselves, but I'm sure there 
are people interested in what you've done. Thanks!
