[Mingw-users] Confusion

[the B. <th...@gm...>]

Hello:

I'm completely mystified as to why the file below won't compile.  It's 
ridiculously simple, and compiles using VC6 and VC.NET:

// POINT.H /////////////////////////////////////////////////

#ifndef POINT_H
#define POINT_H

struct Point
{
     int    id;  // the point id
     double x;   // x co-ordinate
     double y;   // y co-ordinate
};

void inputPoint( Point& pt );
void rotatePoint( double angle, Point& pt );
void outputPoint( const Point& pt );

#endif


// RECT.H //////////////////////////////////////////////////

#ifndef RECT_H
#define RECT_H

#include "point.h"

struct Rectangle
{
     int    id;  // the rectangle ID
     Point  bottom_left;
     Point  top_left;
     Point  top_right;
     Point  bottom_right;
};


void inputRectangle( Rectangle& rect );
void rotateRectangle( double angle, Rectangle& rect );
void outputRectangle( const Rectangle& rect );

#endif

// RECT.CPP ////////////////////////////////////////////////

// standard include files
#include <iostream>
#include <iomanip>

// custom include files
#include "rect.h"
#include "point.h"

using namespace std;

// Function: inputRectangle
void
inputRectangle( Rectangle& rect )
{
     // Prompt user for values
     cout << "Enter the rectangle's ID:  ";
     cin  >> rect.id;
	
	cout << "Bottom left corner point:" << endl;
	inputPoint( rect.bottom_left );
	

     return;
}


// Function: rotateRectangle
void
rotateRectangle( double angle, Rectangle& rect )
{
	rotatePoint( angle, rect.bottom_left );
	rotatePoint( angle, rect.top_left );
	rotatePoint( angle, rect.top_right );
	rotatePoint( angle, rect.bottom_right );
}

// Function: outputRectangle
void
outputRectangle( const Rectangle& rect )
{
	cout << "Rectangle " << left << setw(3) << rect.id << endl;
	cout << "Bottom left ";
	outputPoint( rect.bottom_left );
}

// END //////////////////////////////

When I try to compile rect.cpp, I get the following error messages:

g++ -c rect.cpp -o rect.o

If I rename my 'Rectangle' struct to something else, everything is good 
to go.  This begs the question as to whether another 'Rectangle' is 
defined?    If so (or if not) how can I avoid these errors while still 
using Rectangle for the name of my struct?

Thanks,
Cameron
