Conflict with line 572 of CPCServiceSvc.h
@property (nonatomic, retain) USBoolean * free;

What version of the product are you using? On what operating system?
r234.

Please provide any additional information below.

One solution to patch this is to wrap the call to free in a function call which 
doesn't have the Objective-C namespace conflict. See 
https://github.com/gradha/wsdl2obj_google_bugs/commit/73b194b2c2968a9ed70195c4a3
