The VisualC2008 project builds well with VC 2008 Express, and since they use the same source files, I tend to say that it's a bug in the old VC6 compiler. And (looking at Greg's patch) I don't see a reason why a *comparison* shouldn't be allowed here (taking into account that the later compiler version is okay with it). > Please report this using the STR. > > Here's a patch I've been using.. basically casting > instances of 'this' to a (void*) for the equality tests: [patch elided] Wouldn't it be better to use (Fl_Widget *) or maybe better yet (Fl_Text_Display *)? The former, because this is the returned type of Fl::focus(), the latter because this is what "this" is (no pun intended).
