Hint: there are more than 1600 source files in the library. ~40bytes * >1600modules ~~ >64K call it 80K? IFF you include the entire library in your executables in which case the executable will already be including 1800K of library code and initialized static space; not to mention uninitialized run-time memory declared in the lib modules and the application code! I am suggesting adding less than 4% to the size of any executable (not even near that if any sizable modules are included in addition to the tiny library modules)! You do the exercise, I already have in order to convince 250 programmers here at Bloomberg! The savings in headache and debugging to track the fact that someone forgot to add the new version of module 'X' to the library before linking or forgot to move the latest executable to production is worth almost any overhead!
