See comment #1 and #3.  The standard explicitly states that a Fortran
processor must "detect and report" the use of deleted features.  The
do-variable, start, end, and stride are independent entities and each 
should generate a warning.  If you don't want to see possibly 4 warnings,
then use -std=legacy or -w or fix the problem.  I also suspect that if
one doesn't want to see these warnings, one doesn't want to see any other
warnings related to legacy features.
