The idea that for "dos" it is the same is not true, since this is extender
dependant. Some extenders might return virtual size allocated by the host OS
(DPMI host, or include their own swap.

So this is not between dos and the rest, but between real and 32-bit
protected mode (and I leave in the middle what 16-bits protected mode does,
since that is irrelevant for FPC purposes)

And FPC dos programs _are_ protected mode, not real.
