printing uint64_t

[GoogleCodeExporter]

Dear Josh,

when compiling, I noted a lot of 'printf' related warnings ; the point is that 
the same Q specifier is used to print 'size_t' and 'uint64_t' objects,  but in 
32bit arches those are different; I prepared two preliminary patches that fix 
most warnings but not all of them;  the build log after adding the patches is

2&stamp=1371454355

says: 

[printing 'size_t' varies depending on what compiler you're using :

gnu says %zu (or %zx, or %zd but that displays it as though it were signed, 
etc.)
Microsoft says %Iu (or %Ix, or %Id but again that's signed, etc.)
