"The types used for size_t and ptrdiff_t should not have an integer conversion rank greater than that of signed long int unless the implementation supports objects large enough to make this necessary." Presumably the unnamed misc@ poster was unsafely mixing pointers and integer types.
_types.h: increase size of size_t
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.
