MADV_DONTFORK should be a new advice type for madvise, so it isn't
declared in older header files.
Avi, maybe you should add the stuff to solve the OS compatibility
issues.

Hi,
i had the same problem:
My quick fix with Debian 4.0 and Kernel(.org) 2.6.26.3 was to replace
#include <sys/mman.h>
with
#include <asm/mman.h>
in kvm-74/qemu/qemu-kvm.c
(not sure though if this is such a good idea...)
