The difference being that verify() is a declaration, while verify_true()
is an integer constant expression.

OK, I'll prepare the patch along those lines.

In the meantime, I'm also seeing a failure when trying to compile in
rawhide:

xen/xend_internal.c: In function 'xenDaemonFormatSxpr':
xen/xend_internal.c:5775:112: error: 'MAX_VIRT_CPUS' undeclared (first
use in this function)

which was exactly what my patch was supposed to avoid, so I have to
figure out how to convince things to work with xen-devel-4.0.1-6.fc15
headers. :(
