Running the code on perlmonks in 0.72 I got

sizeof('POINT') = 8
sizeof('CURSORINFO') = 20
sizeof('MYSTRUCT') = 12
[download]

on perlmonks you said you got

sizeof('POINT') = 8
sizeof('CURSORINFO') = 16
sizeof('MYSTRUCT') = 12
[download]

  DWORD cbSize; 4
  DWORD flags; 4
  HANDLE hCursor; 4
  POINT ptScreenPos; ->
      LONG x; 4
      LONG y; 4
= 20

So I believe this has been already fixed so I am closing this bug.
