The last time this has been discussed, my recollection is that the
intended (and actual) behaviour is that -pedantic can turn some
warnings into errors. 

The reason is that by default we may be lenient about some constructs
and/or just warn.  But if -pedantic then we may reject such codes because
of them violating some standard text requirements.  

The latent bug is that the documentation does not reflect that
intended and actual behaviour.

I think -pedantic is front-end dependent just like -ansi.
