[RFC][wwwdocs] Mention PR21173 in the news


This patch adds a brief note about PR21173, the already infamous bug
in GCC 4.0.0 that causes silent wrong code generation.

This bug is rising fast on the list of most frequently reported bugs,
where FWIW it is the only wrong-code bug in the top 10 most frequently
reported bugs (it is in position 10 right now).  No other bug has ever
made it to the top 10 this quickly, so I guess we can conclude many
people are running into it.  Which is not surprising, given how easy
it is to make it trigger.

I think it is Just Wrong to make people download a compiler with such
a severe bug that we know about.  I have said previously that IMHO we
should put out GCC 4.0.1 fast.  The only reactions I got were negative,
see the thread here:

And so, we continue to let people download and use a compiler with a
very severe wrong-code bug.  I can't believe we let this situation
continue to exist.  There is not even a plan yet for GCC 4.0.1!

So this patch adds a friendly note on the home page, with a link to the
bug.  Comments?
