You're right, it wouldn't build properly. I'll move the #ifndef __SOFTFP__
to go just before the defines and add the reverted patch to my outstanding 
patch set.

Any chance we can obsolete softfp only builds any time soon? I can't
remember when the last non-VFP ARM was made, but it must have been at
least a decade ago... Are those NetWinder boards still working/in use?
