It's been a while since I submitted a patch, but since this problem
is due to my code I'll be nice and fix it.  Basically, whenever we get
a WM_SYSCOMMAND:SC_MINIMIZE we need to disable the HWND_TOPMOST attribute
and let the X system recognize it.  On a WM_SYSCOMMAND:SC_RESTORE we just
need to reset that attribute to what it was before.

I'm attaching a patch *against the CVS -r CYGWIN tree* because I cannot
get the XWin-4.3.0-42 source available on
http://xfree86.cygwin.com/devel/server/changelog.html
to compile properly, whereas the freedesktop CVS goes thru without a hitch.

It adds a boolean fAlwaysOnTop to the window privates;  caches the AOT value
on a WM_SYSCOMMAND:SC_MINIMIZE and removes top-z attributes from the window;
restores the AOT value on a WM_SYSCOMMAND:SC_RESTORE; and changes the
WM_WINDOWPOSCHANGED event handler to always allow the Windoze DefWindowProc()
to be called (necessary for the changes I did, and doesn't seem to have any
negative effects).
