To follow up, doing this stuff in the dynamic linker would likely improve ABI-compat functionality, making it possible to remap symbols just for binaries/libraries that were detected as being glibc-linked. I'm actually not sure if this will still be relevant by the time we get around to doing it, but it's nice to have the option open. Rich
