Dear,
I received following questions from users before new year holiday.
I'm sorry for delay in reply.
It looks like both case work fine on my site. I need detail information
if the reporters still have problems.

I tried this
/* ron1.h ************************************************************/
typedef int Lightsource ;
extern Lightsource * spotlight_create (float x, float y, float z,
float to_x, float to_y, float to_z, float fov, float red, float
grn, float blu, int type, bool shadows);
/* ron1.C ************************************************************/
#include <iostream.h>
#include "ron1.h"
Lightsource * spotlight_create (float x, float y, float z,
float to_x, float to_y, float to_z, float fov, float red, float
grn, float blu, int type, bool shadows) {
cout << "x = " << x << endl; ;
cout << "y = " << y << endl; ;
cout << "z = " << z << endl; ;
cout << "to_x = " << to_x << endl; ;
cout << "to_y = " << to_y << endl; ;
cout << "to_z = " << to_z << endl; ;
cout << "fov = " << fov << endl; ;
cout << "red = " << red << endl; ;
cout << "grn = " << grn << endl; ;
cout << "blu = " << blu << endl; ;
cout << "type = " << type << endl; ;
cout << "shadows = " << shadows << endl; ;
return ((int*)NULL);
}
/* COMMAND LINE on Linux */
$ makecint -dl ron1.dll -mk makeron1 -H ron1.h -C++ ron1.C
$ make -f makeron1
$ cint ron1.dll
cint> p spotlight_create(1,2,3,1,2,3,1,1,2,3,1,0)
x = 1
y = 2
.
.
So, it is working as it should. Will you debug into G__cpp_ron1.C file
for more detail? Or just looking into that file may give you some idea.

I tried above program on Linux and it worked fine on interpreter. Will you
tell me your computer platform and version of the interpreter?
