Wouldn't it be better to ignore the intrinsic if it doesn't belong to the 
selected standard?

I would expect --std=f95 to allow the user to define and call user functions 
with the same name as (nonstandard) intrinsics. We resolve intrinsics to 
special names, so the user would still get link errors if they tried to use 
nonstandard intrinsics.

An option to warn/error about nonstandard intrinsics would probably be a good 
idea, but I don't think it should be directly tied to --std=.
