Anyway, I noticed that if I include in a file, I have to include after it if I want to receive warnings for converting non-pointer types to NULL. I guess presume NULL is a macro evaulting to 0 in windows.h and a typedef for (void *)0 in , or? Since I want to have this warning, the approach I've taken is to always include after . Is approach correct and safe or can it get me in trouble?
