No, one cannot call a C subroutine with a variable argument list,
for the simple reason that it is prohibited.  See page 400

  "A Fortran procedure interface is interoperable with a C function
   prototype if ... the prototype does not have variable arguments
   denoted by the ellipsis".

In fact the two C prototypes that your example translates to
have different type and are neither compatible with one another
nor with printf.  I.e. it would not be standard C either.
