- True. Perhaps the inclusion of warnings (and the ability to
- selectively turn them off) is what will differentiate vendor X's
- compiler from vendor Y's. People could put this down on their
- requirements list when shopping for a compiler; if a vendor's
- compiler isn't robust, they could shop elsewhere. Marketing by
- word-of-mouth will hopefully prod compiler vendors to include
- warning also.

- Hello? Anybody on the comittee want to answer this?
