Does anyone know of a convenient way to determine at compile-time (C preprocessor time, actually) which version of headers are being used? I know there are macros in "AvailabilityMacros.h" but that's not applicable to the problem I have.

In early versions, there is not typedef for "socklen_t".

So, is there a #define somewhere which I can test?? Or a more appropriate solution?

Generally it's considered better practice to test for exactly the functionliaty that you require. Does your project have a configure script? If so, you could make that check of socklen_t is defined, and conditionally typedef it if needs be.
