Subject: [U-Boot] warning: dereferencing pointer '({anonymous})' does break
 strict-aliasing rules

I ran Software Update on my Fedora 13 system, and now whenever I build
U-Boot, I get a bunch of warnings like this:

dlmalloc.c: In function 'malloc':
dlmalloc.c:2252: warning: dereferencing pointer '({anonymous})' does break

Can anyone explain why this is happening?  I don't understand how a Fedora
update would change anything, since my cross-compile toolchain is not
distributed with Fedora, so it shouldn't have changed.
