I think this is a good idea, but that first patch is a huge patch for
this point in the 3.1 release cycle. Can we fix the warnings
by just casting the arguments to the img::format() function ?

It only affects the disassembler, which is a debug tool.
A week ago this would have been a fairly definite "yes, fix it"
issue; at this point, with rc3 due to go out today, it's a bit
trickier to justify. (rc3 will be the last rc unless any showstopper
issues turn up.)

My Windows cross-compiler builds work OK, FWIW, and -Werror is
only enabled by default for Linux builds, so warnings shouldn't
result in build failures.
