Re: [9fans] subtracting pointers on amd64 6c

[cinap_lenrek@felloff.net]

what if we introduce signed intptr type and use that instead
of introducing ptrdiff? ape already has a signed intptr_t
type.

then use 'z' as a modifier to mean "intptr size" so that
%zd would print signed intptr and %zud is for uintptr?

the %t and %T space seems rather crowded...
