Subject: [PATCH 1/8] Avoid symbol reference from library to hosting program

Instead of passing the date string or callback reference as
function arguments, getCompileDate() is called directly.

This breaks linking the library with "--no-undefined" and will
lead to a program abort it the program does not provide the symbol.
