/* Defines the macro RTNAME(n) which decorates the external name of a runtime
* library function or object with extra characters so that it
* (a) is not in the user's name space,
* (b) doesn't conflict with other libraries, and
* (c) prevents incompatible versions of the runtime library from linking
*
* The value of REVISION should not be changed until/unless the API to the
* runtime library must change in some way that breaks backward compatibility.
