akz 57c28b6122 0022972: Eliminate macro definitions that has compiler-provided analogs (WNT and so on)
1) Macro definition WNT replaced by _WIN32 and _MSC_VER for platform and compiler detection accordingly.
2) Macro definition LIN replaced by __linux__ macro.
3) Macro definition DEB replaced by OCCT_DEBUG macro.
