Separate patches, please!  I look forward to seeing what you've done.
It would be nice if they were against 0.37.

That's a shame.  At some point, let's get those errors reported
so we can get them fixed (either by the uclibc folks, or by the

Hrm.  Maybe you should take the patches from ptxdist instead.

Hrm.  Maybe the following is related?
