build errors in qcontiguouscache.h on Linux

Hi

I'm switching from Qt 4.5.3 to Qt 4.7 beta for my project. The Qt 4.7 built OK. When I link it to my project, I get some build errors in qcontiguouscache.h. I don't use qcontiguouscache in my project.

I'm using gcc 4.1.2 on RHEL 5.3. I got this problem only on Linux, the windows build is Okay.
Any ideas?

Thanks,
