 // These "special" warning flags are effectively processed as f_Group flags by the driver:
 // Just silence warnings about -Wlarger-than for now.

@rsmith I wasn't super sure about this hunk of the diff.  Should I not be reusing the same flag between the Frontend and the Driver? (The Driver comes after the Frontend, IIUC? Is that right?)
