What's the problem exactly?

I had a problem with printing uint64_t values portably between
the AMD 64 and i386.  My debug printfs had to use either
"%lx" or "%llx".  The workaround (hack) was to use CPP
liberally (#define U64FORMAT "%l" or "%ll").

I wonder if there is a better (more portable) way.
