I wonder if the following code being under an MSDOS conditional is an
oversight, since it mentions GNU/Linux:

  #ifdef HAVE_X_WINDOWS
  /* We need a little extra space, see ../../lisp/loadup.el and the
     commentary below, in the non-X branch.  The 140KB number was
     measured on GNU/Linux and on MS-Windows.  */
  #define SYSTEM_PURESIZE_EXTRA (-170000+140000)

Thanks.
