Probably not all of them. -Wfloat-equal has no effect because there's no FPU 
code in Xen.

The flags  -Wmissing-prototypes -Wnested-externs -Wredundant-decls
and -Wimplicit-function-declaration    resulted in the patches I sent 
yesterday and today.
These flags guarantee that future patches have a higher quality.

For the xen-kernel itself I'm not yet through with these flags.
Nonetheless, I can send a patch you will like. :)
