Building binaries for older versions of libc6

["Ben Hutchings" <ben.hutchings@businesswebsoftware.com>]

I have a C++ program which requires g++ 3.4 to build due to parser bugs 
in older versions of g++.  I'm currently building on a development 
machine running mostly woody with some packages from sarge, including 
g++-3.4 of course.  This requires version 2.3.2 of libc6 itself, and any 
binaries I build with it appear to require version 2.3.  Now, while I 
prefer to do development on Debian, I need to build binaries that will 
run on Red Hat Enterprise Linux 2.1, which has version 2.2.4 of libc6.

I'm wondering whether it's possible to build binaries with g++ 3.4 that 
will require only libc6 2.2, and if so, how.  If I remove g++-3.4, 
downgrade to woody and then build and install g++ from source, is that 
likely to work?

Ben.
