Declarations and Definitions

This object is being defined with external linkage in a source file in which it is never used. Perhaps it could be defined in one of the modules where it is used. This might improve maintainability

For example: 


/*PRQA S 2017,3408,3447 ++*/

int        gb = 0;            /* Message 3211 */
int        gc;                /* Message 3211 */

extern void foo(void)
{
    return;
}
