This is separate from the .2 ABI topic, but what would you think about removing glibc ABI-compat from the current .1 ABI and replacing it with enhanced gcompat? I was thinking ldso could load libgcompat instead of returning a reference to itself for DT_NEEDED referencing libc.so.6, and we could move all ABI-compat symbols into gcompat. The reason I bring it up is that ripping out the LFS64 unwantedly-linkable stuff while keeping it as ABI-only is looking like more of a pain than I expected. Rich
