It was declared as "pid_t", which would be fine except that none of the places that printed it in error messages took any thought for the possibility that it's not equivalent to "int". This leads to warnings on some buildfarm members, and could possibly lead to actually wrong error messages on those platforms. There doesn't seem to be any very good reason not to just make it "int"; it's only ever assigned from MyProcPid, which is int. If we want to cope with PIDs that are wider than int, this is not the place to start. Also, fix the comment, which seems to perhaps be a leftover from a time when the field was only a bool? Per buildfarm. Back-patch to 9.5 which has same issue.
