Ahh.. now I remember the subtle change.  In 4.7 and older,
some managers were considered required.  Now no
managers are considered required.

confdefs.h didn't change that much between 4.7 and 4.8
except to add new managers.  After 4.8, you have more
options but the defaults should be the same as before.

Out of curiosity, did your linked executable get smaller?
Could you share with us the change?

Thanks.
