You can safely ignore these.  The problem is that string constants are  
const char*, and implicitly casting them to char* drops the  
qualifier.  As string constants are, by definition, immutable, any  
attempt to modify them will cause a run time abort.  People often  
write char* when they mean const char* though, so it's not really a  
problem.

I think you can turn this option off with -Wno-write-strings or  
something similar.

This one just looks strange.  I can't think of any situations where  
this would not work.  What is the code that is causing it?  You should  
be allowed to cast from a void* to any pointer type, and at the most  
this kind of cast should raise a warning, not an error.
