It looks like this has been broken for a very long time, but it must
never have mattered before because libpq-fe.h is so stable, and
pg_regress doesn't use any new-ish APIs from it. So pulling in
whatever version the platform had still worked.
I think this should work to fix it:
-pg_regress.o: override CPPFLAGS += -I$(top_builddir)/src/port -I$(libpq_srcdir) $(EXTRADEFS)
+pg_regress.o: override CPPFLAGS := -I$(top_builddir)/src/port -I$(libpq_srcdir) $(EXTRADEFS) $(CPPFLAGS)
but I haven't tested yet.
