Suppress warnings for unused variables using a compiler option
Currently, the generated code suppresses warnings for unusued variables by assigning to the "_Val" variable, for example: _Val = Tmpval5 To be completely safe, that should have been: _ = Tmpval5 in case there happens to more than one such assignment in the same scope. However, a better way to suppress warnings is to simply use the 'nowarn_unused_vars' compiler option. That method will also work for more complicated expressions there it would be cumbersome to suppress warnings by assignment to "_".
