I am having trouble getting classes set up in DJGPP.  The problem is that
gpp gives me the error:  "palette.c:9: return type specification for
constructor invalid" when I try to compile.  If I comment out the
constructor, then it gives me the same type of error for the destructor.
Also, if I try to declare DCColor in palette.h and implement it in
palette.c, then I get these errors on compile:

In file included from palette.c:5:
palette.h:10: field `paletteArray' has incomplete type
palette.c:12: warning: multiple types in one declaration
palette.c: In method `DCPaletteType::DCPaletteType()':
palette.c:24: confused by earlier errors, bailing out

Anyone have any idea what I am doing wrong?

Here are the files that are giving me problems when I compile...

/* palette.h */
#ifndef DCPALETTETYPE
#define DCPALETTETYPE

typedef struct DCColor
{
    unsigned char red;
    unsigned char green;
    unsigned char blue;
};

class DCPaletteType
{
    private:
        char * filename;
        DCColor paletteArray[256];

    public:
        DCPaletteType();
        ~DCPaletteType();
        int Load(char * path, char * filename);
        int Save(char * path, char * filename);
        int Import(char * path, char * filename, int format);
        int Export(char * path, char * filename, int format);

}

#endif



/* palette.c */
#include <stdio.h>
#include <alloc.h>
#include <process.h>
#include <string.h>
#include "palette.h"


DCPaletteType::DCPaletteType()
{
    int counter;
    for (counter=0; counter<256; counter++)
    {
        paletteArray[counter].red=0;
        paletteArray[counter].green=0;
        paletteArray[counter].blue=0;
    }
}

DCPaletteType::~DCPaletteType()
{
}

int DCPaletteType::Load(char * path, char * filename)
{
    return 0;
}

int DCPaletteType::Save(char * path, char * filename)
{
    return 0;
}

int DCPaletteType::Import(char * path, char * filename, int format)
{
    return 0;
}

int DCPaletteType::Export(char * path, char * filename, int format)
{
    return 0;
}



Thanks!
