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.
Right. We can't assume because a *_r function is missing that the normal function is thread-safe.
getpwuid_r, will y'all declare that UnixWare has thread-safety?
My vote is YES.
