I am also somewhat uneasy about calling it "char &c".  The consistent way to
declare it would be "char *&c", since you have to write "&c" to get ahold of
the "char *" object you are really using.

The problem, as your last example points out, is that the notation "{...}"
doesn't distinguish between different structure types.  I suppose the cast
notation is workable, but kinda ugly.

No, the last example requires assigning each member to a temporary, and then
passing that temporary as an argument.
