Turbo Pascal and Janus Ada compilers/linkers at least do eliminate
every unused data/code in the final EXE.
But these languages (Ada, TP) are modular and the linker can be
reliabily informed that such and such code in .o files won't be used.

When you have a graphics package, you are not expected to use every
routine in it, are you ?
