I have just started to use DJGPP to program in C and I am having some
problems.  I am now splitting my program into seperate files and I am
having some problems with the header file.

I define the structures like this in my C code:

struct spriteDef
{
 int x;
 int y;
 int imageNumber;
 int stillValid;
 };

struct spriteList
{
 struct spriteDef spriteDefParams[64];
 } spriteList;

and I define them in my header file like this:

extern struct spriteDef
{
 int x;
 int y;
 int imageNumber;
 int stillValid;
 };

extern struct spriteList
{
 struct spriteDef spriteDefParams[64];
} spriteList;

Every time I go to compile, I get told I have made an empty declaration,
but the problem is- I don't know how I should properly define the
structure.  Can anyone help me?

Sorry if the answer is really obvious, but I don't have much experience
of programming in C.

Thanks,
Dave Peterson.
