Fix 32-bit SSIZE_MAX POSIX requires that SSIZE_MAX have the same type as ssize_t, but on 32-bit, we were defining it as a long even though ssize_t resolves to an int. It also requires that SSIZE_MAX be usable via preprocessor #if, so we can't cheat and use a cast. If this were newlib, I'd have had to hack _intsup.h to probe the qualities of size_t (via gcc's __SIZE_TYPE__), similar to how we already probe the qualities of int8_t and friends, then cross our fingers that ssize_t happens to have the same rank (most systems do, but POSIX permits a system where they differ such as size_t being long while ssize_t is int). Unfortunately gcc gives us neither __SSIZE_TYPE__ nor __SSIZE_MAX__. On the other hand, our limits.h is specific to cygwin, so we can just shortcut to the correct results rather than being generic to all possible ABI. Signed-off-by: Eric Blake <eblake@redhat.com>
