WINGDIAPI void APIENTRY error in gl.h

I am using OpenGl for win95 and cannot get even a simple program (the
first in the Programming OpenGl book) to compile. I get LOTS of errors
in gl.h about the section of code that resembles:

WINGDIAPI void APIENTRY GLsomefunction ( paraeters....)
....
....
....

I have wing installed and have included the proper header files (I
think) and nothing works. I know this is a simple problem but I can't
figure it out for anything. Any ideas or insight???

TIA,
Tom.

You must include <windows.h> before <GL/gl.h>.

That worked like a charm. don't know why I didn't think of it earlier
but know I am getting unresolved externals... in VC++4.0. Back to the
manuals...

error LNK2001: unresolved external symbol __imp__glFlush@0

Can't get any simpler than this..

#include <windows.h>
//#include <GL/Gl.h>
#include "f:\OpenGL\glut.h"

void display(void)
{
//clear all pixels
glClear(GL_COLOR_BUFFER_BIT);

//draaw a white polygon
glColor3f(1.0,1.0,1.0);
glBegin(GL_POLYGON);
glVertex3f(0.25,0.25,0.0);
glVertex3f(0.75,0.25,0.0);
glVertex3f(0.75,0.75,0.0);
glVertex3f(0.25,0.75,0.0);
glEnd();

glFlush();
}

void init(void)
{
//select background color
glClearColor(0.0,0.0,0.0,0.0);

//init viewing vlues
glMatrixMode(GL_PROJECTION);
glLoadIdentity();
glOrtho(0.0,1.0,0.0,1.0,-1.0,1.0);
}

int main(int argc, char** argv)
{
glutInit(&argc, argv);
glutInitDisplayMode(GLUT_SINGLE | GLUT_RGB);
glutInitWindowSize(250,250);
glutInitWindowPosition(100,100);
glutCreateWindow("hello");
init();
glutDisplayFunc(display);
glutMainLoop();
return 0;

You must add opengl32.lib to your library link list. If you use any of
the glu* entry points (not glut!) you must also add glu32.lib.

I know this is a horrible question, and I really should be ashamed of
myself for asking because I have been using C for almost 3 years
now...but,

How do you link in .lib files??? I know the fucntion definitions are in
those files, but I can't figure out how to link them with the .obj's to
build the executable. Is it in options->preferences? Do you have to do
it from the command line? Can you put some lines in a make file and do
it that way??? I tried that, and my program "made" without errors, but
when I ran it, it performed an illegal op in the kernel module.
(kernel32.dll) Funny thing is, it was one of Kilgard's example programs
that I was building. heh heh...

Anyone who can help...please do. :)
