  Gnulib module: mkstemp
  
  Portability problems fixed by Gnulib:
  @itemize
  @item
  This function is missing on some platforms:
  mingw, MSVC 14.
  @item
  On platforms where @code{off_t} is a 32-bit type, @code{mkstemp} may not work
  correctly to create files 2 GiB and larger.  @xref{Large File Support}.
  @item
  On some older platforms, @code{mkstemp} can create a world or group
  writable or readable file, if you haven't set the process umask to
  077.  This is a security risk.
  @end itemize
  
  Portability problems not fixed by Gnulib:
  @itemize
  @end itemize
  
  The gnulib module @code{clean-temp} can create temporary files that will not
  be left behind after signals such as SIGINT.
