I havie now seen Yossi's code, and re-read his original post:
"...when you remove the first such line which contains single line comment , the compiler stops to show all other places where such comments occures."

As I've said many times before, you must always look first at the first message reported by your compiler; always fix that initial message first before moving on to subsequent messages.

Almost invariably, one message early in the compilation will "confuse" the compiler, and cause it to generate many more confusing messages throughout the rest of the compilation. These will disappear as soon as you remove the original source of the confusion.
