The Jones are tough to keep up with when the documentation for -r8 is so sparse. These complaints are noted.  For V3.0 we followed the precedent set by V2, knowing the holes w/r/t the specifically single-precision intrinsics.  

Thanks for raising the issue.  Specifically single-precision intrinsics
always ought to be replaced by their double precision equivalents when compiling with -r8.  Note also that -r8 affects REAL declarations but not REAL*4 declarations (presumably your code depends on the size allocated if you're using the non-standard declaration form).
