Subject: Re: [PATCH] Fortran 2018 rounding modes changes

Hello,

I'm coming (late) to this.

If we accept the argument, we have to support it somehow.
So for IEEE_GET_ROUNDING_MODE (*, 10), we should return IEEE_OTHER, 
shouldn't we?
There is no problem for IEEE_SET_ROUNDING_MODE (*, 10) as there is no 
way this to be a valid call if radix 10 is not supported, but changing a 
compile time error to a runtime unexpected behavior seems like a step 
backwards.
