Replacing GNU make 3.81 with 4.4.1 was trouble free. I then applied the
following diffs (slightly changed from my previous msg). This built
with GCC 13 on Linux but not with GCC 14 because there is a bug in
src/sbin/gpt/ involving confusion between pointers to int and long, and
GCC 14 will not up that nonsense. 

I'll look at the gpt source code tomorrow.
