Sorry, I cannot find anywhere in the standard that one has to emit four
warnings. First, I think that one warning for a real loop variable is enough
(if the loop variable is integer, but e.g. step is real, I of cause expect a
warning there). Second, one can also emit a warning stating:

Warning: Deleted feature: Loop variable and start, stop, and step expression at
(1) must [all] be integer [but are all real]

where [...] is optional text to really stress that all four constrains are
violated.
