collect2 will detect these symbols when they exist in shared libraries that

the current program is being linked against. All such initiliser functions

will be called prior to the constructors of the current program, and

finaliser functions called after destructors.

only invoked once in the case of multiple dependencies on a library.

-binitfini is still used in parallel to this solution.

collect2 will detect these symbols when they exist in shared libraries that

the current program is being linked against. All such initiliser functions

will be called prior to the constructors of the current program, and
|

|
finaliser functions called after destructors.
|

Reference counting generated by collect2 will ensure that constructors are

only invoked once in the case of multiple dependencies on a library.

-binitfini is still used in parallel to this solution.
