In the log message of that commit I don't see any app mentioned or bug number
referenced. Besides, not only DefWindowProc behaviour already contradicts the
above commit, but spy++ also clearly shows that WM_SYSCOMMAND/SC_CLOSE is
posted, not sent under Windows. What kind of other proof would you prefer to
see?
