ssize_t appears to be incorrectly defined in types.d, which unistd.d imports. It is supposed to be a "signed" size_t, whereas there are aliases in it that make it size_t. For example, OSX's /usr/include files definite set it to be a long, not a size_t as set in types.d. It looks like all the aliases need to be double checked.

I tried the uninspired name ssize_t; the problem is it conflicted with unistd.d and I couldn't disambiguate due to what seems to be a compiler bug.

I meant to use sizediff_t as a temporary until we settle on a final solution. When we do, I'll replace that symbol with whatever we settle for.

But now we have:

ptrdiff_t
sizediff_t
ssize_t

all aliased to the same type. What's the rationale for when one uses which?
