RE: [ECOS] Problems with gcc-3.0.3 building arm toolchain

["Dan Conti" <danc at fullplaymedia dot com>]

I think the recommended tools might still be the 2.9x stuff. And,
really, this isn't an eCos issue. But i've built gcc 3.0.3 without a
hitch on cygwin so chances are you are missing something.

You probably need to change more than just the gcc packages. i.e. you'll
want to build binutils 2.11.2 with this, and you'll probably want to
build insight 5.1.1 with this too (since it appears to handle gcc 3.x
generated code better).

That being said, i suggest reading through the following email on how to
build a cross toolchain. Note that the symlinking he suggests didn't
work for me on cygwin, but you can get the same effect by untarring the
first package, renaming the directory, untarring the second, etc.

If you have more problems, you should probably hit one of the gcc lists.
