What is the "correct" way to tell which version of FreeBSD you're
building on using #ifdef's in your C source code?

Specifically, I have the problem that a file requires

  #include <net/if_var.h>

when building under 3.0, but not when building under 2.2 (the file
doesn't exist under 2.2).

Thanks,
-Archie
