Thanks - that is a good reference, and it looks that gcc9 is implementing the
new recommended best practice.  Does anyone active in SG14 know if existing
practice was surveyed before making this recommendation?  My testing has been
limited to C++ compilers, and I believe there are a wider range of C vendors
that may be relevant than my little survey had access to.
