That's right. For the conversion of a non-trivial integer(4) expression to real(4) warnings are desired. But for a known integer(4), one could use the knowledge of the Fortran model of reals a check whether the modulus of the integer is smaller than 2/epsilon(0._4). (I hope that I got the factor of two correctly). -- http://gcc.gnu.org/bugzilla/show_bug.cgi?id=42809
