* Source/win32/WIN32Server.m: * Source/win32/w32_movesize.m: Fix a rather serious error where the extra window data was allocated in two places (allocated with objc_malloc in the WM_CREATE handler, and also allocated by Windows using the cbWndExtra field of the window class structure). Sometimes the window level was accessed from one memory area and sometimes from the other. This is a quick fix that leaves the level and ordered properties in the cbWndExtra area, and the rest is left in the WIN_INTERN structure. This fixes the problem where window ordering was broken when running apps in gdb. git-svn-id: svn+ssh://svn.gna.org/svn/gnustep/libs/back/trunk@31198 72102866-910b-0410-8b05-ffd578937521
