Really?  trap is a shell built-in; it makes the shell that runs the
Makefile command ignore the HUP signal, as does the gv process.  But the
Emacs kill-compilation command and the compile-internal utility call
interrupt-process, which sends the INT signal; compile-internal then
calls delete-process, which calls Fkill_process, which sends a QUIT
signal.  So I don't see why ignoring HUP would have any effect on that

sequence of actions.
