why not introduce the new _external_ interface, go around eliminating 
all known uses of the old.  once done (new release made?) zap the old 
interface.  a common pratice is to add code to the old interface to 
issue a warning the first time it is called.

alan's basic problem of needing to co-ordinate everything so it can all 
happen at once just goes away.

it also covers the k&r problem - you cant rely on a k&r compiler to 
report parameter mismatches.
