Not likely. Only if you open the binary and read data from it.

No, this is more that some units in the past were not smartlinkable.
Moreover, already compiled units (RTL etc) might not be compiled with
smartlinking enabled.

The only real problem with smartlinking that I'm aware of is that
smartlinking as currently done on _huge_ binaries (>5-10MB code) eats up
massive (GB+) amounts of mem. On a new system for smartlinking is being
worked on (this will be used in paralel, since not all OSes support the
new system)

No real idea. Does libgettext.so exist btw? Maybe it can't find the
dynamical lib.
