I would personally separate return 0 + <stdio.h> change (exit() + <stdlib.h> replacement into separate commit) and printf() => puts() into it's own commit. It's unrelated to the preprocessor change, it'd be slightly easier to read the change (you're actually changing 3 things in single commit). > The only C program that took command line arguments, and therefore > needed to declare main with arguments, is replaced with a > preprocessor-only check and string manipulation from shell. +1 > Wherever possible, uses of printf are demoted to puts. What was the reason of this? Both are in <stdio.h>, right? Kind regards, Petr
