It's even worse with code which you're trying to have be cross-platform 
between 32-bit and 64-bit. Microsoft added I32 and I64. which helps, but then 
you still need to add a wrapper to printf for Posix to handle them unless you 
want to ifdef all of your printf calls. About the only positive thing that I 
can say about that whole mess is that it's because of that that I learned that 
string literals are unaffected by macros in C/C++. The fact that I can just do 
%s with writefln in D and not worry about it is so fantastic it's not even 
funny.
