Surely this is wrong.  You might be able to assume that Windows'
definitions for min/max are the same as what this code is expecting,
but it's a lot bigger stretch to assume that for the other ones.
(Does tsearch2 still *work* after you change it this way??)

The right thing for the min/max macros is to get rid of them anyway,
and use the Min/Max macros from c.h.
