Package: gcc-3.3
Version: 1:3.3.2-0pre1
Followup-For: Bug #207915
MontaVista hit the same problem. Here's the patch (written by Michael
Eager) we're using to avoid it:

In other words, make GCC think that the maximum length of a short branch is
64K instead of 128K. It's a big hammer, but it works.
We're also using this:
