You're right, it does give a "warning" if you use -Wall.  But on the 
default warning level, the program has two major errors, which should 
not be considered warnings.  It has a non-void function, which is used, 
not returning a value, and a void function (main()) returning a value.  
Every other compiler I've used spits out error messages for these 
problems.  This is a big problem, not a "INVALID" concern.

Also, did you notice the void function
