If the Empty Declarations option is on, the compiler displays a warning when it encounters a declaration with no variable name. For example:

int ;                // WARNING
int i;              // OK

The Empty Declarations option corresponds to the pragma warn_emptydecl, described at "warn_emptydecl." To check whether this option is on, use __option (warn_emptydecl). See "Checking Options" for information on how to use this directive.
