Of course I can upgrade to glibc-2.0-whatever-date is needed. It just does
not change the facts. Binaries created with that setup will not run on
an older installation.
To get back where I started: I never said the patch did a bad thing. If it 
had been in egcs half a year ago, there would not be any of the problems
we currently face.
I'm just looking for a solution, a system that will run older binaries,
newer binaries and - on the other side - compile binaries that will
themselves run on newer and older installations.

I was never asking to revert that patch, but I was asking for a clue.

with kind regards (mit freundlichem Grinsen),
