Yep, it's the extra template parameter which is confusing the compiler. If you have parameters it can't 
deduce from the input to a function, they must be given explicitly, so in this case that function is just 
ignored. This has been wrong since it was submitted (version 1.19 of the file). Removing that extra 
template parameter is the right thing to do. I had a quick look at other functions submitted at the same 
time and they are fine, so it's just a copy+paste bug I suspect :)

Hopefully gcc will eventually get clever enough to remove empty loops by itself, and then we won't need 
these types of hacks, but for now this is the right patch to apply.
