#     minmax: fix up min3() and max3() too
#     
#     David Laight pointed out that we should deal with the min3() and max3()
#     mess too, which still does excessive expansion.
#     
#     And our current macros are actually rather broken.
#     
#     In particular, the macros did this:
#     
#       #define min3(x, y, z) min((typeof(x))min(x, y), z)
#       #define max3(x, y, z) max((typeof(x))max(x, y), z)
#     
#     and that not only is a nested expansion of possibly very complex
#     arguments with all that involves, the typing with that "typeof()" cast
#     is completely wrong.
#     
#     For example, imagine what happens in max3() if 'x' happens to be a
#     'unsigned char', but 'y' and 'z' are 'unsigned long'.  The types are
#     compatible, and there's no warning - but the result is just random
#     garbage.
#     
#     No, I don't think we've ever hit that issue in practice, but since we
#     now have sane infrastructure for doing this right, let's just use it.
#     It fixes any excessive expansion, and also avoids these kinds of broken
#     type issues.
