First of all, I would consider polite to CC: me on the mail if you quote and
debate my statements.

Where exactly do I say that it is wrong to provide a patch that makes GCC
better in this regard? As a bugmaster, I just decided to consider this not a
bug, in the strictest meaning of "bug". If you want to file in Bugzilla an
enhancement proposal about adding options/modes about higher FPU precision, I
would not object.

Also, it seems you have the wrong belief that, if bug 323 were confirmed in
Bugzilla, a patch would automatically appear. I think the two events are
totally unrelated, especially for an issue which has been debated so much in
the past years, and where most people have already a formed opinion on the
matter.

You seem to believe that a patch can be accepted in GCC only if it fixes a bug.
That is wrong: a valid patch can also add a new feature. While it is probably
hard to convince the Powers That Be (which, by the way, are surely not me) that
the default setting of GCC should be whatever Bug 323 requests, it is much much
easier that a patch adding a new command line option to request higher FP
accuracy be reviewed and accepted. Of course, people would have to *see* such a
patch. And nobody is blocking people from writing it.

I hope to have clarified my position.
