There is a bunch of warnings on the latest build of GNU APL for Mac OS 14.7.6:

==============================
Also, there is an option on the ld command that should probably be removed in
the makefile:
==============================
checking for -single_module linker flag... ld: warning: -single_module is
obsolete
no
ld: warning: -bind_at_load is deprecated on macOS
==============================
