Ah, oops. As it turns out the patch is for the ARM tools only, and it
appears you are compiling the other tool suite. I have now made a new patch
for that.

The only problem is that I can't reproduce the problem you had with readline
on a RH6 box here.

They were included mostly for the benefit of those Unix platforms that do
not come with GNU tools by default. eCos specifically requires GNU make. If
you already have GNU make, you could save a little build time by simply
deleting the make subdirectory.

I would expect the newly released gcc-2.95 ( http://gcc.gnu.org/ ) should
work fine. The next release of eCos is likely to move towards us showing you
how to grab the latest release of the net stuff, rather than a monolithic
tarball.
