-fpermissive was a compromise between the desire for stricter conformance
checking and the desire for backwards compatibility with users' code, so
that users would be able to use newer compiler versions while they update
their code.  I still feel strongly that this is an important goal, but I'm
open to other ideas about how to implement it.
