[Dev-C++] Programming with multiple modules/files

[<and...@su...>]

Dear users,

   Please consider the following project-file
cenario:
///file1.c///////
#include "global.h"
main()
{
   func_x();
   a = 100;
   ...
}
///file2.c///////
extern int a;
func_x()
{
   ...
   a=300;
}
///global.h///////
int a;
void func_x(void);
///////////

My problem is:
   1) I have a lot of file2.c-type files (files with only
      function definitions), a lot of functions
      and several "extern" variable declarations;
   2) Trying to include global.h in file2.c too, avoids
      the need of declaring all extern variables. But this
      action generates warnings of duplicate includes (2 or
      more include global.h);
My question is:
   Is there any way to manipulate several file2.c-type files
without declaring each extern variable?

Regards
Andre Barros
