[Mono-dev] How To Convince Mono To Allocate Big Arrays

We want to keep changes to a minimum and we want to keep default array size
32bits. Renaming from guint32 to whatever_t is API/ABI compatible
if the underlying type keeps been the same. Using 64bits array length
changes the ABI in incompatible ways and that's why Paolo's suggestion of
doing some symbol renaming in libmono to make sure you cannot link between
those two.

I guess the only breaking changes we expect to have are due to the new
garbage collector that requires write barriers.
