True + True = True, because "true" means "not zero" and "false" means "zero". In most all languages that permit int->bool casting, if(2) will evaluate to "true".
The warnings clang and FCC generate are a style warning because it's unclear on casual reading. Even readers who know the precedence rules will typically want to insert the parentheses manually. If the meaning were undefined, the compiler would give an error, not a warning.
