This change is one I can agree with on technical grounds, though it
will cause a great deal of pain in the short term. Have we got any

gets made?
Fedora already made the change a full release cycles ago, and Fedora

I can't see why you think --as-needed is fundamentally wrong or unnecessary.
It is fundamentally wrong because -lfoo means I demand that the
initializers of libfoo.so run, whether or not I called anything in it.
So it's more like static linking. 8-)
