It's not a language violation, nor could ever be one.  So why would the
compiler warn about it? 

Also there are many instances where you would assign an int to a char. 
For example, the tolower(), toupper(), etc macros. 

If you want these sorts of warnings use a lint tool like splint .   But
better yet is to use data types you require and not just ones you pick
willy-nilly.
