G21 Compatibility Call
The compiler provides a special
cc219x
use of existing libraries with the new compiler. The extern
declaration can be added to the prototype(s) of the functions developed

after the C code is upgraded to use the new compiler.
This convention is similar to the C++/C linkage specification.
