Yes, and that is the complex part because _some_ non-*_r functions are
thread-safe, and some are not.  I have to determine if we have other
such platforms before I figure out how to fix it in the cleanest way.

In most platforms that are like this, I think, they have all the *_r
functions even if all of them are not required.
