Exactly that's the difference: pam_stack is recursive, include
is including. Means there is no difference if you use include or
put the modules into the config file, but there is a big difference
if you use pam_stack (return value of all pam modules only count
for pam_stack).

pam_stack was RedHat/Fedora only, meanwhile replaced by include.
