In version 8.40 I get a compilation warning message that I was not getting in earlier versions for the following code:

Code:
Module m
  Integer, Parameter, Public :: dp = Kind(1.0d0) ! - double precision -
  Integer, Parameter, Public :: sp = Kind(1.0e0) ! - single precision -
#if DP==1
  Integer, Parameter, Public :: rp = dp          ! - default precision -
#else
  Integer, Parameter, Public :: rp = sp          ! - default precision -
#endif
!
  Real(Kind=rp), Parameter, Public :: million = 1000000.0_rp ! - one million -
End Module m


I compile with /CFPP /VPARAM DP 1

The error message is:

A REAL constant has been trucated with possible loss of precision

Sorry about this. We are still getting the occasional false error report with this new test for loss of precision. I have fixed this particular failure for the next release after v8.40.

Thanks, Paul. Does that mean that the error report is spurious and I can simply ignore it?
