C-bindings generator from Fortran

It was written to automate generation of C bindings for Fortran, source code can be found here.

! Example of input Fortran90 code:
module SomeModule
  use iso_c_binding
  implicit none
  real*8, bind(c), parameter  :: dbl1 = 1.0d0
  type(c_ptr), bind(c, name="ptr1") :: ptr1
contains
  integer function SimpleFunction1() bind(c, name="SimpleFunction1")
    integer :: a
    integer b
    integer :: c
    !...
  end function SimpleFunction1
end module SomeModule

// Generated C-bindings:
#ifdef __cplusplus
extern "C" {
#endif

typedef void* some_ptr_t;
typedef double val_t;
double dbl1;
void* ptr1;
int SimpleFunction1();
#ifdef __cplusplus
}
#endif
