This isn't an issue - you define the new prefix to point to
the old name, e.g.:

     #define opjt_foo fsgjt_foo

The compiler and linker use the old names, as before.  The
developer can use the new names and be none the wiser.

Another method is to provide shim functions for all of the
old names, calling the new names.  That has a performance
impact, however, so I recommend using #define instead.

Enumerations and other constants can be done the same way...
