Thanks for reminding me.
I have tried again using

Target: i686-pc-linux-gnu
Configured with: ../gcc/configure --prefix=/opt/GCC/4 --enable-threads=posix
--enable-languages=c,ada,c++,fortran
Thread model: posix
gcc version 4.3.0 20070127 (experimental)

This compiler appears to be working.

***

FWIW, the Ubuntu 6.10 system compiler gives a variation of the
original error for attachment 10359.
