  I think the problem is posix saying that is* needs to process EOF
without deciding if "char" is signed or not.
  isspace(foo[3]) has been around for a *LONG* time. It shouldn't break.
I will fix my code to use unsigned char's, fine, but I suggest that gnu-win32
make char unsigned by default then.
