Re: [ECOS] building c library package..using eCos Configuration tool 1.3.1

[Andrew Lunn <andrew dot lunn at ascom dot ch>]

There error comes from GCC3.x. This is not the recommended tool chain
for ARM. You should be using a gcc 2.x tool chain as documented on the
Installation instructions.

Secondly, 1.3.1 is very, very old. I suggest you update to the latest
version using anoncvs. You may then find that gcc 3.x does work, but
its still not the recommended tool chain so you may still get problems
with it.
