It turns out this is next to impossible to do: some DPMI hosts lie
about the largest allocation they can satisfy.

So in the next release of DJGPP, malloc will fail any attempt to
allocate more than 2GB - 64KB + 1 (we subtract 64KB because sbrk
rounds up the allocations to the nearest multiple of 64KB, before it
asks the DPMI server for more memory).
