commit d30c08f30da9fb043598ebbb8609b4a4447e0cef Author: Stefan Reinauer reinauer@chromium.org Date: Thu May 2 14:02:28 2013 -0700
Make ssize_t an actual ssize_t
In the process of getting rid of compiler includes during in coreboot and libpayload, we defined size_t and ssize_t ourselves, using a GCC macro for size_t: __SIZE_TYPE__. Unfortunately, there is no __SSIZE_TYPE__, so we temporarily redefine unsigned to signed to make __SIZE_TYPE__ __SSIZE_TYPE__.
