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.

logic in collect2.

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.

This handles the case where a library is loaded through dlopen(), and also

handles the option -blazy.
