int*_t and uint*_t (not u_int*_t) are standard in C99, and they are
available in stdint.h or inttypes.h (both work, inttypes.h contains also
the PRI* constants for the corresponding printf() format specifiers).
Perhaps it would be better to use one of those headers instead? That
would require converting u_int*_t usage to uint*_t, though, so it would
take some extra work...
