Attached program gives error on mips-sgi-irix6.5, but not on i686-pc-cygwin or SGI f90

Error is:
j.f: In program `MAIN__':
j.f:14: 
         i3 = ISHFT(i,BIT_SIZE(i))
              ^
Reference to intrinsic `ISHFT' at (^) invalid -- one or more arguments have incorrect type


According to F90 standard (section 15.13)
* the first arg of ISHIFT is integer type
* the second arg of ISHIFT is integer type
* the return type of BIT_SIZE is same as argument
* the return type of ISHFT is same as the first arg
