Thanks for your patch!

Based on that, I applied the patch below, which also adds a new section
for C/C++ and one for Java, and has a couple of other minor fixes.

(For example, it's UltraSPARC, not Ultrasparc, and there must not be
a line break directly after "<a href=...>", or we will have an extra
blank.)

PS: Andreas, Jan, please have a look at the x86-related changes, and
feel free to update them as you see fit.
