        2 functions with some indirect sub-type change:

indirect sub-type changes:
            Please note that the exported symbol of this function is

            return type changed:
              in pointed to type 'struct utmp' at utmp.h:58:1:
                type size hasn't changed
                1 data member changes (1 filtered):
