The line it shows is, clearly, wrong (the scanner has already gotten to
the next line by the time the parser has recognized the situation).  On
the other hand, the preceeding for is bodyless.

FYI:
If you use {} instead of ; after the 'for()' the message will vanish,
since  {} stands out enough that it is surely not a normal human typing 
mistake.

Sorry about the line shown being the wrong line....
