[Dev-C++] Structure

[<chr...@cr...>]

Who help me ? If i compiled this project with devcpp 4.9.6, i have messages
:

3 C:\Dev-Cpp\struc.c [Warning] `struct Forme' declared inside parameter
list
3 C:\Dev-Cpp\struc.c [Warning] its scope is only this definition or
declaration, which is probably
not what you want.
 C:\Dev-Cpp\struc.c   [Warning] In function `change_structure':
5 C:\Dev-Cpp\struc.c dereferencing pointer to incomplete type
6 C:\Dev-Cpp\struc.c dereferencing pointer to incomplete type
 C:\Dev-Cpp\Makefile.win  [Build Error]  [struc.o] Error 1

Thanks for your help.

main.c

#include <stdio.h>

struct Forme
{
int type;
int couleur;
};

void change_structure(struct Forme *Forme);

int main(int argc, char *argv[])
{
  struct Forme cercle;

  change_structure(&cercle);
  printf("cercle.type %d\n", cercle.type);
  printf("cercle.couleur %d\n", cercle.couleur);
  system("PAUSE");
  return 0;
}

struc.c

void change_structure(struct Forme *Forme)
{
 (*Forme).type=0;
 (*Forme).couleur=1;
}
