For the record, we're not going to muck with anything. Also for the record, we have no plans of tracking every single micro release of stdcxx 4. Upgrading to micro releases is TBD, based on what the new rev actually introduces. The development cycle of stdcxx often uses micro releases to address bugs specific to a particular compiler/architecture combo. This isn't always relevant to Sun Studio/Solaris. If it isn't relevant, why fix it when it ain't broken ? > That is, even though the incompatibly evolving C++ language definitions and > associated rickety scaffolding may allow one to shoot themselves in the foot, > and their code could be evolved in ways that would expose such runtime > binary incompatibilities, they explicitly promise not to do so within a > certain set of release naming boundaries. > > What more can the ARC ask?

We [ SFW/KDE ] were going to introduce this library in Nevada/OpenSolaris -- it's the easiest integration, and it's the one we care most about, because it can be done *now*. 2. They [ DevPro/Tools ] were going to introduce this library with the compiler(s), for Solaris 9/10, at some point in the future. I cannot say when that will be. Is this agreement still valid ? Or has it been filibustered ? --Stefan -- Stefan Teleman Sun Microsystems, Inc. Stefan.Teleman at Sun.COM
