The problem with this is that the automatic determination (in configure)
whether there is a xxx_r()  version is, in general, fragile.  We cannot
rely on configure saying that xxx_r() doesn't exist, so the plain xxx()
should be good enough.  Else, we'd be shipping claimed-to-be-thread-safe
libraries that might trigger bugs that will be hard to track down.

I don't see any other solution than keeping a database of NEED_XXX_R for
each platform and then requiring these functions to show up before we
declare a library to be thread-safe.  So far we're only dealing with three
functions, to it should be doable.
