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>:
0x501 2003sdk
0xa00 win10 sdk
