Hello Anthony,
A quick search on google produced the following:
../../src/glibc-2.6/configure --prefix=$HOME/glibc32-2.6 \
--host=i686-linux-gnu \
--build=i686-linux-gnu \
CC="gcc -m32" CXX="g++ -m32" \
CFLAGS="-O2 -march=i686" \
CXXFLAGS="-O2 -march=i686"
You could give this a go and see how you get on.
The poster claims that it was successful. I don't have a 64-bit system
so am unable to verify it.
Regards,
Christopher.
