// The following includes of STL headers have to be done _before_ the

// definition of macros min() and max(). The reason is that many STL
|
|
// implementations will not work properly as the min and max symbols collide
|
|
// with the STL functions std:min() and std::max(). The STL headers may check
|
|
// for the macro definition of min/max and issue a warning or undefine the
|
|
// macros.
|
|
//
|
|
// Still, Windows defines min() and max() in windef.h as part of the regular

// Windows system interfaces and many other Windows APIs depend on these

// macros being available. To prevent the macro expansion of min/max and to
