Do you happen to know if Vista is a genuine minimum requirement, in
this case? Or, must we just take this on faith?
I'd personally just ignore the "minimum version part". I guess you want to
surround this by NT version number check, correct?
Yes.
Just checked Win10 SDK - only surrounds CONSOLE_SCREEN_BUFFER_INFOEX by
"not phone" (the COMMON_LVB_ attributes are not surrounded and I assume
they just don't do anything on Win95/Win2k)
I wouldn't be too confident about that: normal behaviour of Microsoft APIs is
to crash, when passed a flag which they don't understand ... even if the flag
may be defined for a later version of the API. My concern is that exposing new
flags, unconditionally, may lead to unexpected run-time application crashes, on
legacy OS versions, where an appropriate #if guard block could catch the
potential for crashing, at compile time. We need to either accept the Microsoft
documentation at face value, of we need to devise a test for safety of such
flags on legacy OS versions ... and to find testers who can run that test on a
multitude of legacy Win32 versions.
Note: cmd replacements like ConEmu may support these on older OS versions,
too.
Really? Even if the supporting API isn't provided by the underlying (legacy) OS
version? That would imply that ConEmu, (or other terminal emulator), provides
its own fall-back emulation of such APIs: not impossible, but by no means a
trivial task; seems kind of improbable.
Also note: ConEmu is not a cmd replacement; cmd.exe is a shell; AIUI, ConEmu is
a terminal emulator ... a container in which a shell is run, (and that shell
may well be cmd.exe).

Ticket details:
The current one seems very outdated.
It misses some older things (I was told that this is around since 2007) like
the CONSOLE_SCREEN_BUFFER_INFOEX structure
1. typedef struct _CONSOLE_SCREEN_BUFFER_INFOEX {
2. ULONG cbSize;
3. COORD dwSize;
4. COORD dwCursorPosition;
5. WORD wAttributes;
6. SMALL_RECT srWindow;
7. COORD dwMaximumWindowSize;
8. WORD wPopupAttributes;
9. BOOL bFullscreenSupported;
10. COLORREF ColorTable[16];
11. } CONSOLE_SCREEN_BUFFER_INFOEX, *PCONSOLE_SCREEN_BUFFER_INFOEX;
and the newer COMMON_LVB_ defines for CHAR_INFO structure such as
1. #ifndef COMMON_LVB_GRID_HORIZONTAL
2. #define COMMON_LVB_GRID_HORIZONTAL 0x0400 /* Top horizontal */
3. #endif
4. #ifndef COMMON_LVB_GRID_LVERTICAL
5. #define COMMON_LVB_GRID_LVERTICAL 0x0800 /* Left vertical */
6. #endif
7. #ifndef COMMON_LVB_GRID_RVERTICAL
8. #define COMMON_LVB_GRID_RVERTICAL 0x1000 /* Right vertical */
9. #endif
10. #ifndef COMMON_LVB_REVERSE_VIDEO
11. #define COMMON_LVB_REVERSE_VIDEO 0x4000 /* Reverse foreground and
background attribute */
12. #endif
13. #ifndef COMMON_LVB_UNDERSCORE
14. #define COMMON_LVB_UNDERSCORE 0x8000 /* Underscore */
15. #endif
Note: all these are included in mingw-w64 since some time but I think the
original should be updated, too :-)

Comment:
This official Microsoft documentation page indicates that the COMMON_LVB
attributes are supported from Win2K onwards. This unofficial legacy
documentation page does not mention them, which suggests that they may not have
been supported prior to Win2K.
Certainly, this is an opinion based on conjecture, but I think it may be
appropriate to place these definitions within an #if _WIN32_WINNT >=
_WIN32_WINNT_WIN2K exposure guard block.

.. @keith - Do we have something to commit now?
No. I now have three patches, but I'm not yet entirely satisfied with them.
Specifically:
1. _WIN32_WINNT specific symbol visibility guards are inadequately defined;
many symbols are visible to compilations for legacy Windows versions, for
which they may not be applicable.
2. Bit-flag values should be specified in hexadecimal -- as Microsoft do in
their on-line documentation -- not in decimal, as they are at present, in
our <wincon.h>; this may make no difference to the compiler, but it is
sub-optimal for human interpretation.
I'm working on it, but I'll need a few more days to finalize it. In the
meantime, you're welcome to try the two patches I've attached so far. My third
patch will be more significant; it already addresses item (2), but not yet (1).
I will not publish it, until I've dealt with that, by which time the series of
three should be ready to commit.
FTR, the lack of a formal ChangeLog entry, to accompany David Gressett's
initial patch, will introduce a delay ... because I will have to write it for
him.
