Micrsoft's compiler gives the warning in the Subject when compiling
various GTk+ files. I have previously ignored them, but now I thought
maybe it's best to ask if they might be a sign of some bugs lurking in
the code...
For instance, the following lines in gtktext.c cause that warning:
(line numbers from my current win32 codebase, approximate for the CVS
version)
1109:
move_mark_n (&text->cursor_mark,
-MIN(nchars, text->cursor_mark.index - text->point.index));
1491:
gdk_gc_set_ts_origin (text->bg_gc,
(- text->first_onscreen_hor_pixel + xthick) % width,
(- text->first_onscreen_ver_pixel + ythick) % height);
3579:
scroll_int (text, - LINE_HEIGHT(CACHE_DATA(text->line_start_cache->next)));
3625:
gint pixels = - text->first_cut_pixels;
3822:
pixel_height = - text->first_cut_pixels;
