Summary0038014: Concatenating an array with += does not compile
DescriptionThis is a follow up to 0037913.

If COperators are enabled and ModeSwitch ArrayOperators is set then using "+=" for an array should compile. FPC simply expands A +=B to Concat(A, B) (adding a single element is expanded to Insert(B, A, Length(A))).

Example is attached.
