suppress_checking

["Juanma Barranquero" <lekktu@gmail.com>]

Is there any point to the variable suppress_checking, or is it leftover code?

It is defined (and initialized to 0 by default, but not otherwise
modified in any way) in alloc.c, and the only use is in lisp.h:

  /* Extra internal type checking?  */
  extern int suppress_checking;
  extern void die P_((const char *, const char *, int)) NO_RETURN;

  #ifdef ENABLE_CHECKING

  #define CHECK(check,msg) (((check) || suppress_checking		\
  			   ? (void) 0				\
  			   : die ((msg), __FILE__, __LINE__)),	\
  			  0)
  #else

  /* Produce same side effects and result, but don't complain.  */
  #define CHECK(check,msg) ((check),0)

  #endif

Now, I suppose it could perhaps be useful while debugging, but if
that's the intended use, it's undocumented and quite a bit obscure...
