Thanks for committing this!

Just a small nit: Using inline functions with internal linkage to
implement standard library functions isn't 100% conforming.

7.1.2#6:
  Any declaration of a library function shall have external linkage.

7.1.4#2:
  Provided that a library function can be declared without reference to
  any type defined in a header, it is also permissible to declare the
  function and use it without including its associated header.
