There used to be a fairly standard set of #defines along this line that were
added to <stdio.h> or some other standard header file. Something like
#define strcpy DONT_USE_STRCPY
#define strncpy DONT_USE_STRNCPY
#define strcat DONT_USE_STRCAT
#define strncat DONT_USE_STRNCAT
#define gets DONT_USE_GETS
#define sprintf DONT_USE_SPRINTF
I don't think it was standard in any platform, though. More of an ad hoc
measure.
