What if we define the function this way, with const on the second argument (instead of casting to char * on the function call)? Does that also get rid of the warning?

void lcd_implementation_drawedit(const char* pstr, const char* value)

I apologize for the late reply,

void lcd_implementation_drawedit(const char* pstr, const char* value)

it's possible.

With #3176 it encouraged the use of const in more places where it should be used anyway. It's a magic word, that const, though it has many mysterious meanings.
