Subject: _proxy_pda still makes linking modules fail

This is linux-2.6.20.1 with lots of patches from PLD Linux (I believe
the patches don't affect the issue), compiled with gcc-4.1.2 and
binutils-2.17.50.0.12 on x86.

Linking the kernel causes warnings:

Linking modules fails:

I've heard that it now builds with gcc-4.2.0 snapshots. This is strange:
if the problem has been fixed for gcc-4.2.0, why doesn't it work for
gcc-4.1.2? arch/i386/kernel/vmlinux.lds.S does contain _proxy_pda = 0;

I'm not subscribed to the list.
