It sure looked like they were live functions.  I'll have a look.

Oh, the install-headers-cris and disabled install-lib?  Sorry, I
should have pruned that.  Though using "make install-headers"
and "make install-lib" seems buggy; I haven't got anything else
but "make all" and "make install" to work usefully.  Hmm, I
should save that for a separate report when I've had time to
investigate it more thoroughly.

Well, it won't fly *without* it at the moment.  Perhaps it
should've been added as a generic flag.

I didn't see how to fix the glibc macros easily.  I might have a
look at fixing the assembler, presumably how to merge the
attributes sanely.

> One more comment: which is the first kernel supported?

Hmm, good question, actually.  At least it's no earlier than
2.4.2, as mentioned in the documentation patches, but it might
also be 2.4.3.

Thanks, I'll have a closer look at that.

Thanks!

And thanks for the quick turnaround.  The fewer differences to
the FSF tree, the happier the local maintainer. ;-)
