I think this would be usefull.  Currently I have to use something like this:
	#ifndef BUFSIZ
	# include "? Whoops - BUFSIZ not defined"
	#endif

I think this would be usefull; and harmless.  I often redefine routines
(in different include files of course):
	extern char *retstring () ;
	extern char *retstring () ;

If I sometimes changed retchar to a macro, I would want to be able to have
the following in both my include files also:
	#define retstring(s)	"s"
