Indeed. If you can find sources, which aren't encumbered by an exclusive
licence, that's fine; for example, from this GitHub page, I deduce that
{{{ code cs
internal const uint PROC_THREAD_ATTRIBUTE_PSEUDOCONSOLE = 0x00020016;
}}}
A further example: on pinvoke.net I see
{{{ code
PROC_THREAD_ATTRIBUTE_PARENT_PROCESS = 0x00020000,
PROC_THREAD_ATTRIBUTE_HANDLE_LIST = 0x00020002
}}}
with terms of use which grant us complete freedom to use this information,
subject to us accepting any liabilities for any consequence of such use.
I can suggest this:
https://github.com/mozilla/positron/blob/master/security/sandbox/chromium-shim/base/win/sdkdecls.h

Ticket details:
To compile programs that use the Pseudo Console feature introduced recently
with Windows 10, there's a need in several additions to the MinGW w32api
headers and import libraries.
First, we need a value for _WIN32_WINNT that specifies Windows 10, in
sdkddkver.h:
#define _WIN32_WINNT_WIN10 0x0A00
Second, we need functions, data structures, and macros to create and update
lists of attributes for process and thread creation. These are:
InitializeProcThreadAttributeList function
UpdateProcThreadAttribute function
DeleteProcThreadAttributeList function
PROC_THREAD_ATTRIBUTE_LIST structure
STARTUPINFOEX structure
PROC_THREAD_ATTRIBUTE_PSEUDOCONSOLE macro
Other PROC_THREAD_ATTRIBUTE_* macros
These seem to be supported since Windows 7, with the exception of
PROC_THREAD_ATTRIBUTE_PSEUDOCONSOLE, which is only supported since Windows 10,
and STARTUPINFOEX, which is supported since Vista. I think the proper place
for them is in the winbase.h header file.
We also need the EXTENDED_STARTUPINFO_PRESENT flag for the CreateProcess
function (this flag is supported since Vista and should be in winbase.h).
And finally, we need the functions, data types, and macros to manipulate
pseudo-consoles, available only since Windows 10:
CreatePseudoConsole function
ClosePseudoConsole function
ResizePseudoConsole function
HPCON data type
Thanks in advance for providing these.

Yes, I stumbled upon that myself. It all looks kind of back-to-front, to me;
e.g., predicated on #if _WIN32_WINNT < 0x0602, (i.e. < _WIN32_WINNT_VISTA), it
sets about defining features which are unsupported prior to Vista.
Furthermore, apart from the mitigation policy properties suitable for use from
Win8 onwards, it doesn't appear to define anything for which I haven't found a
more useful reference, and it has what appears to be an unnecessarily
convoluted mechanism for defining properties such as
PROC_THREAD_ATTRIBUTE_HANDLE_LIST ... possibly inspired by a study of
Microsoft's headers, although, since I have not examined (and will not examine)
those myself, I cannot be certain.
FWIW, within this golang code review, I see
const ( + // attributes for ProcThreadAttributeList +
PROC_THREAD_ATTRIBUTE_PARENT_PROCESS = 0x00020000 +
PROC_THREAD_ATTRIBUTE_HANDLE_LIST = 0x00020002 +
PROC_THREAD_ATTRIBUTE_GROUP_AFFINITY = 0x00030003 +
PROC_THREAD_ATTRIBUTE_PREFERRED_NODE = 0x00020004 +
PROC_THREAD_ATTRIBUTE_IDEAL_PROCESSOR = 0x00030005 +
PROC_THREAD_ATTRIBUTE_MITIGATION_POLICY = 0x00020007 +
PROC_THREAD_ATTRIBUTE_UMS_THREAD = 0x00030006 +
PROC_THREAD_ATTRIBUTE_PROTECTION_LEVEL = 0x0002000b +)and can see no
documented restrictions, which would prohibit us from using this as a reference
source.
