-Downgrade messages about nonconformant code from errors to warnings. By
-default, G++ effectively sets @option{-pedantic-errors} without
-@option{-pedantic}; this option reverses that. This behavior and this
-option are superseded by @option{-pedantic}, which works as it does for GNU C@.
+Downgrade some diagnostics about nonconformant code from errors to
+warnings. Thus, using @option{-fpermissive} will allow some
+nonconforming code to compile.
