// The most annoying are #defines of many identifiers that you could use in 
// normal code without knowing that Windows has its own knowledge of them...

// If someone needs more from windows.h, he is encouraged to #undef these symbols
// or include windows.h prior to any OCCT stuff.
// Note that we define each symbol to itself, so that it still can be used
// e.g. as name of variable, method etc.
