There are 2 reasons for not committing it as-is:
  1) The spec of gethostname() in Windows is different from the one in Unix,
     see [1]. In particular, it does not set errno, and requires prior use of
     WSAStartup().
  2) It requires the introduction of a Makefile variable LIBGETHOSTNAME.

See also the discussion that started in [2].
