Produce a warning-free build on ppc64 (at least, when built as 64-bit
userspace -- if a 64-bit binary for ppc64 is a requirement, why is -m64
set only on purgatory?). Mostly unused (or write-only) variable
warnings, but also one nasty one where reserve() was used without a
prototype, causing long long arguments to be passed as int.
