There's also a MessageBox function in the unit LCLLinux.  This function
takes four parameters instead of three; the first parameter is the handle of
the owning window.  In the win32 interface, LCLLinux's MessageBox function
creates a native message box but Application.MessageBox creates a
cross-platform message-box-esque window.
