Hm - here uClibc-0.9.20 doesn't even compile out of the box.
I'm using binutils 2.13.2.1, gcc 3.2.3 with the fixes and patches from
buildroot.

after some random hacking and stumbling over another 'bug' [1] it compiles
at least. I had no time to test it on the cris itself......See attached
diff.
Using buildroot, with the uClibc snapshot I get even more strage
errors:
