Create a new section of pyport.h to hold all external function declarations for systems that are missing those declarations from system include files. Start by moving a pointy-haired ones from their previous locations to the new section. (The gethostname() one, for instance, breaks on several systems, because some define it as (char *, size_t) and some as (char *, int).) I purposely decided not to include the summary of used #defines like Tim did in the first section of pyport.h. In my opinion, the number of #defines likedly to be used by this section would make such an overview unwieldy. I would suggest documenting the non-obvious ones, though.
