I’m ok with this version.

I’’ve asked Jack for the header in question that makes max/min ambiguous.  I think this is a bug in the system libraries, that said, I’m ok with working around the bug in the wide-int source code as expedient.  I think including string in system.h is unfortunate, and I think the whole do_not_use_toupper_with_safe_ctype thing is unfortunate.  Unless someone wants to reengineer ctype… or require the removal of string and all other system headers that are not in system.h…  I think this is as good as we can do for now.
