// 6g accepts the program below even though it is syntactically incorrect:
// Each statement in the list of statements for each case clause must be
// terminated with a semicolon. No semicolon is present for the labeled
// statements and because the last token is a colon ":", no semicolon is
// inserted automatically.
//
// Both gccgo and gofmt correctly refuse this program as is and accept it
// when the semicolons are present.

// This is a test case for issue 777 ( http://code.google.com/p/go/issues/detail?id=777 ).
