As a total beginner when it comes to writing a part of a fortran compiler, I 
had a look at the "not" intrinsic function.

I must have misunderstood very many important things, it can't possible be 
this easy, can it?

// the code in my file:   gcc/libgfortran/intrinsics/not.c

#include "config.h"
#include <sys/types.h>
#include "libgfortran.h"

extern GFC_LOGICAL_4  not (GFC_LOGICAL_4 l)
{
        return !l;
}

extern GFC_LOGICAL_8 not (GFC_LOGICAL_8 l)
{
        return !l;
}


I noticed that the other files are using iexport_proto and export_proto_np, 
but I have no clue about what they do.

So, should I find something else to do than bugging you with my code, or 
should I start working with another intrinsic function?
