I had to do the following:

- upgrade the debian package binary (i.e.libc and libc-dev) to 2.1
  this went smoothly and required only a few upgrades.

- build install the new libc to /usr/local

without upgrading the debian libc packages, my version of gcc (namely a 
self-built egcs 1.1.2) would fail to build the libc.

I think you can savely downgrade the debian packages when done to 2.0
again, to have a slink installation and no half-upgraded system. 

You then can use your self-comiled libc for developing and such - but
you cannot uninstall debian libc without breaking major dependencies
and having to rebuild large parts of your system manually ;-)

Tilman.
