What about -D_REENTRANT?

I was under the impression that the requirements for pthreads were
-D_REENTRANT (or the equivalent #define in the code) at compile time and
-lpthread at link time. I've never heard of this -pthread compile time
option, and neither has the GCC manual. Could you explain please?
