Here's an alternative based on a mix of Daniel Wallin and Goran 
Mitrovic's code. I believe it is standards compliant. And, in theory, 
can allocate up to 4096 ids. It should be easy to extend it do more, 
although compile times will probably put you of doing that.

The problem is, that to use it you have to set the type index at the 
global scope and it can't be called from a template. Because of that, it 
doesn't offer much advantge over using the preprocessor to allocate ids 
and would probably result in larger compile times.
