WANRS=6 cleanup for vidcontrol(1):
- Use foo(void) instead of foo(). - Use static where applicable. - Apply more const's when passing parameters - signed/unsigned madness - Avoid namespace collision by adding underscores. - For 64-bit architectures, use %zx instead of %x when necessary. - When storing constants, use const instead of variable. - Bump WARNS?= from 2 to 6
