[Xen-devel] xen build error on gcc v4.5.0

["Masroor Vettuparambil" <Masroor.Vettuparambil@xxxxxxxx>]

I got the below error when I do a 'make world' in xen-testing.hg . The kernel 
is 2.6.31.14. gcc version is 4.5.0. 
It is working with gcc v4.3.0
Btw  I thought the default kernel in xen-testing.hg is 2.6.32.x, but it is 
still 2.6.31.x.
