PATCH: bugs.html and GCC 3.1

[Gerald Pfeifer <pfeifer at dbai dot tuwien dot ac dot at>]

We actually fixed two of the ABI bugs in GCC 3.1.
Also update and compress the general notes

(The first I verified by checking all PRs mentioned in the text; the
second probably is a consequence of some paper compression I had to
do recently. ;-) )

-Also, a related, but more obscure case is when both that and an <code>operator

-functions, it is incompatible with the ABI. GNATS PR 113 tracked this,
