And there's a lot of confusion about whether you have to throw in 
-D_REENTRANT as well (on GNU/Linux and on other systems).

I think on GNU/Linux, pthread detection mostly happens at run time these 
days, and you ought to use the _r API variants (which are available 
without -pthread) in library code.  I even think you shouldn't link 
against the library unless you actually create threads.
