Well, but this is an amount of time you (as a company) or someone else
upstream has to investigate anyway, sooner or later, right? ;-)
Also, I would expect future releases of G++ to break less and less
existing code, now that there is an ISO C++ standard and G++ sticks
to it increasingly closely. For example, for some project of mine,
we didn't have to change a single line when migrating from GCC 2.95
to GCC 3.0.

Yes, I consider this useful.
