This is one of those really weird situations where POSIX and C disagree
with each other C forbids the conversion and POSIX requires it to be
valid. However, I ran across an example that eliminates the warning. I
guess we have to hope we never wind up on a platform that really has
data pointers that are incompatible with function pointers.
