Fails to link with perl 5.38 and later:

cc  -shared  -L/usr/local/lib -fstack-protector-strong  XS.o  -o blib/arch/auto/Algorithm/Heapify/XS/XS.so

I came here confirm the issue with a similar error log:

If we look at line 1072 of proto.h at perl5 commit 0351a629e71de127cbfd1b142e9eaa6069deabf5

As we can see was updated in the diff but GitHub's deep linking doesn't seem to support the diff-view.
