Right, thanks. I added a comment and committed.
Obviously the longer term fix for that particular issue is not to
define those functions in that header at all. If no one beats me to
it, I'd like to have another look at consolidating all our popcount()
and ffs() functions[1], and this fls()/log2(), pow2() stuff seems like
it might be part of the same refactoring expedition. For now I just
added the missing include guards to unblock some other stuff I'm about
to propose that wants to use simplehash.h.
