+Some GUI structures defined by windows will be larger,
+If (_WIN32_WINNT) value is larger.
+
+Also if we send sizeof(win_gui_struct) to some windows function,
+and we compile that code with big (_WIN32_WINNT) value,
+the window function in old Windows can fail, if that old Windows
+doesn't understand new big version of (win_gui_struct) compiled
+with big (_WIN32_WINNT) value.
+
+So it's better to define smallest (_WIN32_WINNT) value here.
+In 7-Zip FM we use some functions that require (_WIN32_WINNT == 0x0500).
+So it's simpler to define (_WIN32_WINNT == 0x0500) here.
+If we define (_WIN32_WINNT == 0x0400) here, we need some manual
+declarations for functions and macros that require (0x0500) functions.
+Also libs must contain these (0x0500+) functions.
+
+Some code in 7-zip FM uses also CommCtrl.h structures
+that depend from (_WIN32_IE) value. But default
+(_WIN32_IE) value from <windows.h> probably is OK for us.
+So we don't set _WIN32_IE here.
+default _WIN32_IE value set by <windows.h>:
