- atrf-xtal.c (cmp, eval, do_atben): moved to atben.c - atrf-xtal.c (setup, sample, cleanup): removed wrappers - atrf-xtal.c (usage): cast strlen result, for x86-64 compatibility - atrf-xtal.h (atben_setup, atben_sample, atben_cleanup), atrf-xtal.c: device interface functions are now "static" - atrf-xtal.h (do_atben): do_atben is now our new interface
