Hi,

attached a patch that fixes some warnings issued by gcc4 when compiling
Qemu. I know that Qemu does not work with gcc4, but Xen (and KVM) uses 
significant parts of Qemu and this works with gcc4. When
compiling Xen I see a lot of those warnings and miss the serious ones
;-( , the patch fixes some of them (mostly signedness pointer warnings).
Please apply so that the other projects can pull the changes (Xensource 
will not accept pure Qemu patches on xen-devel).

The habit of using typecasts to fix those warnings is debatable, but 
this is the least intrusive approach.

BTW: What was the outcome of this socklen_t issue? I saw both "int" and 
"socklen_t"  in the past, is there a policy regarding this?

Comments welcome.

Best regards,
Andre.

P.S. I haven't found something about the patch submitting policy on
qemu-devel (inline or attachment, cvs diff or {git|hg} diff). Hope that
my approach is OK.
