In theory it should be possible to take the various toolchain
components from the sourceware site and combine them to get a set of
tools usable with eCos. The main components are gcc 2.95 (not any
earlier releases), gdb 4.18, and binutils. It should be possible to
add Insight to that list as well.

In practice there are no guarantees that this will work. gcc, gdb etc.
are all separate projects undergoing rapid development, and we do not
continually test all of the toolchain components for eCos
compatibility. The toolchain download that is available via the eCos
web pages has been specifically tested for eCos and is known to work.

So if people want a solid and tested toolchain than the eCos one is
appropriate. If you want the very latest compiler optimizations etc.
then feel free to try out the latest releases of everything. It is
possible that everything will just work for any given target. It is
also possible that there may be a few problems that you will need to
sort out.
