Windows version fixed

[Thue]

quote: I have fixed the memory leak in the windows-gtk version. The bug was in gdk_gc_set_clip_mask. The was one g_malloc without g_free. The patch is send to the gdk-win people. I have put a new version for windows in the incoming dir of ftp.freeciv.org. freeciv-1.11.4-win.zip-1 The file freeciv-1.11.4-win.zip can be deleted (my internet connection has broken down while uploading). I don't stop working on the native windows port (it is much faster than the windows-gtk port). Greetings Andreas Kemnade
