Following the revalations made by a misc@ poster, I am happy to present
the following patch which increases the width of size_t from "long" to
"long long", which is twice the width as before, on all platforms. This
has the effect of doubling the amount of available memory regardless of
the physical capacity installed memory hardware. Additionally, it
enables PAE on all 32 bit platforms without incurring performance costs.
