Thank you.

Now that I think about it, the if statement that determines if the
int4 specialisation will be used may be okay - it sort of documents
the conditions under which the int4 specialisation should be used with
reference to how the "else" generic case actually works, which is
perhaps no bad thing. I now realise that I should be using constants
from fmgroids.h though.
