The ABI status of ELF hash tables

I don't see the internal details of the structures used by the dynamic linker as much of an ABI myself. Yeah, the old format is mandated by SysV, but I don't care if my linux distribution is SysV compliant. I don't see anything useful provided by the SysV specification at this point. Needless change is wasteful but that exact point in history doesn't seem interesting to me. I also think it's right to chide those responsible for moving us to an undocumented format. It's not something many people will need to know, but a transparent system is a fixable system.

But all that aside, I don't see how symbol namespacing really means something one way or another in this case.
