A solution to the multiple inclusion problem

[Rich Salz]

Gee, if
	#ifndef _HAVE_FOO_H_
	... contents of foo.h ...
	#define _HAVE_FOO_H_
	#endif	/* _HAVE_FOO_H_ */

is too slow, then do this:
	#ifndef _HAVE_FOO_H_
	#include <hidden_real_name_of_foo.h>
	#define _HAVE_FOO_H_
	#endif	/* _HAVE_FOO_H_ */

John's rules about the first #ifndef after the first comment sound much
too complicated for me -- I have enough problem with election day...
