Your mailer has completely mangled the To/From/Cc lines, in violation of
more than one RFC. Please seek out a more competent mailer for future

There's nothing 'special' about the dreamcast. It's a legacy board under
the SH kernel, with no special casing. It doesn't require a special
toolchain or anything else, either. It's worked with gcc 4.x as long as
the SH kernel has supported gcc 4.x. Whatever KOS is smoking is
irrelevant.

There are multitudes of gcc 4.x toolchains available, both in binary and
source. See the Linux/SH wiki for more details: http://www.linux-sh.org.

If you find a build problem in buildroot, it's a bug, so you should log a
bugzilla entry for it. If people don't report bugs, it's difficult to
know what we need to look at.
