Nothing special about <stdio.h> (aka <cstdio>), feel free to remove it 
from every file where, by whatever mechanism, you can prove that it is 
not necessary to include.  (Though it is unclear to me how much removing 
redundant includes of standard headers actually helps"accelerating 
compile times" in practice.)
