	FileInfoBlocks and NewWindows are probably ok.  Stacks must be public
if you plan to call anything that might use a Dos call OR call anything that
might use SignalSemaphores.  This is, of course, all speculation, and all
the MEMF_PUBLICs in the world won't guarantee your program will work if we
do a protected mode OS, but they certainly give your program a much better
chance!

	Which is why I was vague.  Even if I gave a list, it might change
tomorrow (or at least next time we release an OS upgrade).
