Hellow every kind helpers.

I have a simple question.

Can I get rid of the

#ifndef _NR_H_
#define _NR_H_

and

#endif :confused:

Even if it would be something duplicated but not complicated to implement, I guess.

Am I right?

I wouldn't recommend it - the compiler will likely complain about multiple definitions. The whole point of the #ifndef 'sentinels' is to prevent such errors. Hope this makes sense.

this is C/C++ issue, not NR issue.
