Note the mainline version of the watchdog is more up-to-date than the
linuxsh one, iirc.

I recommend stable as being GCC 3.0.4 and binutils 2.13 w/ patches.  The
patches can be found at ftp://ftp.m17n.org/pub/linux-sh/testing/.  Look for
the highest patch revision (0 for GCC 3.0.4 and 6 for binutils 2.11.2).
The binutils 2.11.2 patch should apply cleanly to 2.13.

I have built a GCC 3.2 toolchain (based on uClibc even :P) but I haven't
had a chance to test it yet.  I've attached the patch for 3.2 (Karl, do you
remember the original location of Kaz' 3.1/3.2 patch?).  It should also
apply cleanly to stock 3.2.

Thanks!  I'll grab your patches and integrate them into both the linuxsh
and linuxdc trees.  I've been busy scrambling to get the bitrotten linuxsh
tree up to snuff for 2.5 before the freeze, so I'll probably switch our
experimental linux-sh-dc tree over to 2.5 RSN.
