GB.ReturnNewString() returns a void string only if its length argument 
is zero AND if its value argument is NULL.

If the length is zero, or lower than zero, and if the value is not NULL, 
then strlen() is called on the value.

It behaves like that to be backward-compatible with older version of Gambas.

But then it prints a big warning on the error output to ask to use 
GB.ReturnNewZeroString() instead.
