[C++, wwwdocs] bugs/index.html - complete C++ non-bug entry

[Gerald Pfeifer]

Jason and Nathan,

while I completed one C+ non-bug entry with the patch below, I am
not sure the items as such is really still relevant?

In fact, if you could have a look at https://gcc.gnu.org/bugs/#nonbugs_cxx
and advise which entries perhaps should be removed (or updated or
added), I'll take care.

Thanks,
Gerald

 
Add a missing <dt> element to the C++ Non-bugs section.
