Adding a AC_MODE_T test (to check to see if mode_t is defined in
sys/types.h) to autoconf 1.2 (like is done with size_t, uid_t, and
pid_t) made it a lot easier to move a project of mine from machine
to machine.

The following patch to autconf 1.2 adds the AC_MODE_T test to
autoconfig and updates the on-line documentation.
