YES. I believe UnixWare7 has such.

On all (recent) UNIX systems it toggles on correct handling for thread specific instances of historically global variables (eg errno). It should be considered for all platforms if libpq is intended to be used from threaded programs.Now that I think about it, what that macro is probably really doing is switching the code from looking at a static "errno" variable to looking at a per-thread variable. So in fact -D_REENTRANT would be correct if you intended to link with a thread-aware libc, and wrong if you intended to link with a non-aware libc. (Is there such a thing as a non-threaded implementation of libc on the platforms where -D_REENTRANT does anything?) If this analysis is right then I think we should *not* force _REENTRANT; it will have to be up to users to choose the mechanism they want to use in their programs.
