commit 0985d418cb2d0a5ba56518e9e1fb9a31f3c7ba48
Author: Matt Joyce <matthew.joyce@embedded-brains.de>

Add _REENT_INC(ptr)
Add a _REENT_INC() macro to encapsulate access to the _inc member
of struct reent. This will help to replace the struct member with
a thread-local storage object in a follow up patch.
