This should not be needed. Please verify these assertions:

- In gethostname.c line 76..77 you should have this:

  /* Get winsock2.h. */
  #include <unistd.h>

- In config.status you should have the replacement rules
  GNULIB_GETHOSTNAME -> 1
  UNISTD_H_HAVE_WINSOCK2_H -> 1

- In the generated unistd.h the four lines

  #if @GNULIB_GETHOSTNAME@
  /* Get all possible declarations of gethostname().  */
  # if @UNISTD_H_HAVE_WINSOCK2_H@
  #  include <winsock2.h>

  should have become

  #if 1
  /* Get all possible declarations of gethostname().  */
  # if 1
  #  include <winsock2.h>

- When you add a -E option to that gcc command and look at the resulting
  '# ' or '#line' lines, you should see that this generated unistd.h file
  is being included.

- If you have multiple gnulib-generated unistd.h files and they are not
  equal, please verify that you are using different double-include
  guards in each (like you proposed yourself a couple of weeks ago).
