> But for ensuring that, could you take a look into the file src/rxkad/rxkad.p.h and see what you have defined for MAXKTCTICKETLEN, Michael??

#if defined(AFS_AIX52_ENV)
#ifdef __XCOFF64__
#define	MAXKTCTICKETLEN	      12000	/* was 344 */
#else
#define MAXKTCTICKETLEN		344
#endif
#else
#define	MAXKTCTICKETLEN	      12000	/* was 344 */
#endif

So compiling for AIX 5.2 and using the 64-bit kernel, I'd assume this 
evaluates to 12000, right? It isn't obvious to me where the __XCOFF64__ 
variable is or is not defined.

By the way, I just realized that Nikkes patch extends the above clause 
from AFS_AIX52_ENV to AFS_AIX51_ENV. What other differences/bugs are 
there in the code related to AIX 5.1 vs. AIX 5.2?
