Extra version stuff in glibc?

[Jeff Bailey]

As a quick sanity check, I did an `objdump --private-headers
/gnu/libc/libc.so.0.3'.  IIRC, the version references and definitions
were quite a bit shorter before.

I built glibc slightly differently this time, mind you:

# ../glibc-2.2.5/configure  --prefix= --enable-libio --enable-oldest-abi=2.2.6 
--build=i686-pc-linux-gnu --host=i386-pc-gnu

Whereas before I hadn't been including an `oldest-abi' line.  My
config.status contains:
address@hidden@%2.2.6%g

I will try and go through my notes after work.  Sadly, I've already
wiped the old hurd partition to try and make sure there was no cross
contamination.  I think I made a backup of the files on alpha, though,
if I need to look at those for reference.
