I'm not going to be able to remember exactly.  It might be worth looking
at various proprietary Unixes to see if they've got fprintf_unlocked, but
given the date I don't think I was looking at one of them.  My best guess
is that I simply assumed glibc had it, since it seemed to have _unlocked
variants of all the other stdio functions.
