I'm just digging into the gcc manual and some things are still unclear to me:

When specifying a std, should I always use -pedantic in conjunction?
When using -g, it the standard level sufficient or should I specify level 3, i.e. -g3?
Is it good practice to use -Werror to promote all warnings to errors and -pedantic-errors to promote all pedantic warnings to errors?
