Most OSes don't even have the concept of thread names, so unfortunately
there's no way to do that portably.  I think your best bet is this:

a) Use LoadLibrary and GetProcAddress to check if the function GetThreadId()
exists.  If it does, use it.  If it doesn't, then:
b) Use LoadLibrary and GetProcAddress to load NtQueryInformationThread.
Search online (maybe in the ReactOS source code) to find the exact signature
of the function and structure layout of the output parameter.
