Those programs are wrong, since strcasestr() is in the Implementation
Namespace.  The correct code (assuming one is using autoconf-like
feature testing) would look something like:

#ifdef HAVE_STRCASESTR
/* assume <string.h> already included */
#define my_strcasestr(a, b) strcasestr((a), (b))
#else
const char *my_strcasestr(const char *, const char *);
#endif
