Try this:

==========================================================

/* dll.c */

#include <stdio.h>

extern __attribute__ ((__dllimport__)) void
exe_hello(void);

void __attribute__ ((__dllexport__))
dll_hello (void)
{
  printf ("Are you there, exe?\n");
  exe_hello();

}

==========================================================

/* dll.def */

LIBRARY my_dll.dll

IMPORTS
exe_hello = my_exe.exe.exe_hello

==========================================================

/* exe.c */

#include <stdio.h>

extern void  __attribute__ ((dllexport))
dll_hello (void);

void  __attribute__ ((dllexport))
exe_hello ()
{
  printf ("Yes, the exe is here,\n");
}


int main()
{
 dll_hello();

 return 0;
}
==========================================================

gcc -shared -o my_dll.dll dll.def dll.c
gcc -o my_exe.exe exe.c  my_dll.dll


You can do the same thing with import libs if you want, but
using a def file is much simpler.
