Hi!
It's actually quite strange; the missing include never gave me any issue with any compiler.
That's why I missed it, I guess.
Anyway, thank you for the PR!

Yep. Really strange. It was kind weird that this is simply missing of header inclusion. At the beginning I thought that this is only my problem, but I tried compile on difference branches and issue appears again.
Thanks for a really nice library!
