[issue6729] Add support for ssize_t

Ryan Coyner added the comment: You don't want to do c_size_t = c_void_p because that will prevent type checking. We want c_size_t to be integers; setting it to c_void_p will accept other values. The lines that define c_size_t are doing a sizeof check to determine how many bits the CPU support

Nikolaus Rath added the comment: Ok, apparently the lines that define c_size_t are these: if sizeof(c_uint) == sizeof(c_void_p): c_size_t = c_uint elif sizeof(c_ulong) == sizeof(c_void_p): c_size_t = c_ulong elif sizeof(c_ulonglong) == sizeof(c_void_p): c_size_t = c_ulonglong (side
