As of 20091024, DOS-specific files use up 62KB of pure space. But
overall, we end up wasting 130KB of pure space, because
BASE_PURESIZE starts at 1.47MB, while we need only 1.3MB (including
non-DOS specific files and load history; the latter is about 55K,
but depends on the depth of the top-level Emacs directory in the
directory tree). Given the unknown policy of different DPMI
hosts regarding loading of untouched pages, I'm not going to risk
enlarging Emacs footprint by another 100+ KBytes. */
