In commitf9e572595bI claimed that I'd removed very nearly all the global and static variables from windows/window.c. It turns out that this was wildly overoptimistic - I missed quite a few of them! I'm not quite sure how I managed that; my best guess is that I used an underpowered 'nm' command that failed to find some classes of variable. Some of the remaining function-scope statics were removed completely by commitafb3dab1e9just now. In this commit, I've swept up some more and turn them into fields of WinGuiSeat, where they should have been moved last September. The (hopefully complete this time) list of remaining variables, generated by running this rune in the Windows build directory: nm windows/CMakeFiles/putty.dir/window.c.obj | grep -E '^([^ ]+)? *[bBcCdDgGsS] [^\.]' consists of the following variables which are legitimately global across the whole process and not related to a particular window: - 'hinst' and 'hprev', instance handles for Windows loadable modules - 'classname' in the terminal_window_class_a() and terminal_window_class_w() functions, which allocate a window class reusably - some pointers to Windows API functions retrieved via the DECL_WINDOWS_FUNCTION / GET_WINDOWS_FUNCTION system, such as p_AdjustWindowRectExForDpi and p_FlashWindowEx - some pointers to Windows API functions set up by assigning them at startup to the right one of the ANSI or Unicode version depending on the Windows version, e.g. sw_DefWindowProc and sw_DispatchMessage - 'unicode_window', a boolean flag set at the same time as those sw_Foo function pointers - 'sesslist', storing the last-retrieved version of the saved sessions menu - 'cursor_visible' in show_mouseptr() and 'forced_visible' in update_mouse_pointer(), each of which tracks the cumulative number of times that function has shown or hidden the mouse pointer, so as to manage its effect on the global state updated by ShowCursor - 'trust_icon', loaded from the executable's resources - 'wgslisthead', the list of all active WinGuiSeats - 'wm_mousewheel', the window-message id we use for mouse wheel events and the following which are nothing to do with our code: - '_OptionsStorage' in __local_stdio_printf_options() and __local_stdio_scanf_options(), which I'd never noticed before, but apparently are internal to a standard library header.
