Thanks for the patch... now it brings me right back the same error I get
with the release 'stable' and 'git snapshot, respectfully 2.33.1 and
2.6.34-rc1. I've tried several different builds of GCC (3.2.3, 3.4.3, 4.3.4,
4.4.2) and various releases of binutils (2.15 - no go, 2.17.90, and 2.20.1).
This was after several failed builds after adjusting the CFLAGS and adding
either -Wl,--no-relax and -relax.
