Those warnings were meant to stop you from taking the step that you're 
considering.  EZCA's internal implementation is quite complex, and the 
package does not have any unit tests so we don't know for sure that it is 
still fully functional on more recent versions of Base (we certainly don't 
run exhaustive tests of it against new EPICS releases, unlike the regular CA 
code).

EZCA is not being actively maintained other than to ensure that it compiles; 
the last functional change to the code was made in 1995, and at the APS we 
changed most applications that were using it to call the native CA API 
several years ago.  It is entirely possible that we might stop building and 
maintaining it completely within a year or two.

I would *strongly* discourage you from adopting EZCA, stick with the regular 
CA API which is well documented and much more heavily used.
