So, is there any interest in fixing this?

We can make our own GetTickCount64 built around GetTickCount and call it
when GetTickCount64 is not available in Kernel32.dll. This code supports
Windows 2000 or greater, whereas calling GetTickCount64 directly from
Kernel32.dll supports only Vista or greater.
static DWORD s_wrap = 0;
static DWORD s_lastTick = 0;
static std::mutex s_wrapMutex;
ULONGLONG MyGetTickCount64()
{
std::unique_lock<std::mutex>_(wrapMutex);
DWORD currentTick = ::GetTickCount();
if (currentTick < s_lastTick)
++s_wrap;
s_lastTick = currentTick;
return (static_cast<ULONGLONG>(s_wrap) << 32) + currentTick;
}

GetTickCount64 would solve these problems, since it returns the
numbers of millisenconds since the machine has started.

A simplier approach is to encapsulate the standard clock of your
choice and save in a static member the value of the last get.
Then if the standard clock goes back in time, you return the
saved value + 1.
For clock drift this is fine, one doesn't even have to bother with
the increment for many cases. However there can be major problems
with NTP, daylight savings, and suspend/hibernation states.
