Changed speed_t from long to unsigned long. POSIX.1 requires an

unsigned integral type.  Changing it doesn't seem to cause any
sign extension bugs in /usr/src.  In the kernel, this is partly
because `struct speedtab' and its lookup function are too bogus
to use speed_t's for speeds - they use ints.
