  Gnulib module: gethostname
  
  Portability problems fixed by Gnulib:
  @itemize
  @item
  This function is declared in a different header file (namely,
  @code{<winsock2.h>}) on some platforms:
  MSVC 14.
  @item
  On mingw and MSVC 14, this function has a prototype that differs from that
  specified by POSIX, and it is defined only in the ws2_32 library.
  @end itemize
  
  Portability problems not fixed by Gnulib:
  @itemize
  @item
  This function's second argument type is @code{int} instead of @code{size_t}
  on some platforms:
  Solaris 10.
  @item
  If the given buffer is too small for the host name, some implementations
  fail with @code{EINVAL}, instead of returning a truncated host name.
  @end itemize
