This is the current problem:

Unfortunately, I don't know enough about gcc internals to really dig into 
this.  If someone immediately knows what this is, then great.  Otherwise
I may have to start reading info files.  :)

The warning about 64-bit code on a 32-bit target is worrisome.  Is that
supposed to happen?
