It removed all ocurrences of the following functions : sprintf strcpy strcat The replacements are slprintf, safe_strcpy and safe_strcat. It should not be possible to use code in Samba that uses sprintf, strcpy or strcat, only the safe_equivalents. Once Andrew has fixed the slprintf implementation then this code will be moved back to the 1.9.18 code stream. Jeremy.
