http://gcc.gnu.org/ml/gcc-help/2009-10/msg00302.html :) I have that 
problem too.

I think you're missunderstanding our problem. We aren't linking to a C 
library. gcc 4.4.2 just doesn't compile for a bare metal target (you 
need that in order to be able cross-compile a C library). I think that's 
really a bug, since 4.4.1 and 4.4.3 (i.e. latest revision in the 4.4 svn 
branch) both build fine.

Best regards.
