I still hope that sane person will read this post. And at least agree 
with my arguments.

Smart linking is the norm in the Pascal world, which has long set 
TurboPascal. You found the different of obstacles for the generation of 
reduced-size code, justifying it with the desire to have a fast 
compilation speed and the small size of the compiler itself. But you 
appeals to the fact that the compiler may be placed on a floppy disk, 
and very happy. I do not use a floppy disk. You do not use a floppy 
disk. We do use RAM and flash memory on a few gigabytes and a very quick 
Internet channels. You do agree, compiler size does not really matter. 
Moreover, smart linking feature is a really special quality of good 
compiler. Compiling time? Heh, with separate compilation, search in 
binary tree and mark code as unused is microseconds. And a complete 
including a large library to target binary is disk IO operations and 
already not microseconds, but much more.

If you do not want to do anything in this direction, what to justify 
their laziness empty words?
