    Thank you!
    
    However, when I try to compile it, I get the following error:

    The constants in question are all defined in Size.def,
    and are not redefined or even imported in either BasicFileSys.def or BasicFileSys.mod; however, they are
    defined slightly differently in CardMath.mod,
    which also gives the same error even though it doesn't import Size.def. 
    
    I checked that the -fiso option was
    not the deciding factor in this, and it wasn't. I'm not sure why it
    is behaving differently on my system.
