It would appear that you are not familiar with the realities of dynamic
linking on UNIX-like operating systems.  Dynamically linked libraries
(we are not talking about Windows DLLs here) are carefully versioned and
tend to become incompatible with their predecessors pretty regularly.
That's why you need to compile a program using dynamic libraries with
the corresponding header versions for the API versioning.

It is a quite special case to explicitly load a shared executable (and
call its entry points) for which not particular headers were used in the
preparation of the binary.  I do not even know the library/system call
for that.
