Bug ID: 51529
           Summary: CloseHandle(INVALID_HANDLE_VALUE) returns FALSE,
                    GetLastError is ERROR_INVALID_HANDLE
           Product: Wine

          Hardware: x86-64
                OS: Linux

Test CloseHandle(INVALID_HANDLE_VALUE)
CloseHandle(INVALID_HANDLE_VALUE) returns FALSE, GetLastError is
ERROR_INVALID_HANDLE on Wine. I tried it with MacOSX and Linux.
But on Windows CloseHandle(INVALID_HANDLE_VALUE) returns TRUE. So many programs
could fail if they didn't expect FALSE here.
Test case (Pascal). Can be compiled with FPC or Delphi.
// file TestCloseHandle.lpr
program TestCloseHandle;
{$APPTYPE CONSOLE}
uses
  //Winapi.Windows;
  Windows;
var
  aHandle: THandle;
  aResult: HRESULT;
begin
  //aHandle := 0;
  aHandle := INVALID_HANDLE_VALUE;
if CloseHandle(aHandle) then
    aResult := 0
  else
    aResult := GetLastError;
Writeln('Result: ', aResult);
end.
