Actually, <windef.h> DOES check if min and max are already defined before
defining them.  But <complex> uses std::max, which won't work if max is a
macro.  The correct fix, in my opinion, would be to update windef.h to not
define min and max if __cplusplus is defined, since C++ is much less
forgiving of min and max being macros in the first place (in other words,
min and max as macros only works in C).

But where does upstream windef.h live, to propose a patch to it?
