Comment 3 Philipe Mulet CLA 2005-10-14 18:39:25 EDT 
Added support. Tuned existing test suites.

* COMPILER / Reporting Unreferenced Label
*    When enabled, the compiler will issue an error or a warning when
encountering a labeled statement which label
*    is never explicitly referenced. A label is considered to be referenced if
its name explicitly appears behind a break
*    or continue statement; for instance the following label would be considered
unreferenced;   LABEL: { break; }
*     - option id:         "org.eclipse.jdt.core.compiler.problem.unusedLabel"
*     - possible values:   { "error", "warning", "ignore" }
*     - default:           "warning"
