I recently compiled Emacs for GTK twice.

The first time configure said (in its summary) it was still building for Lucid, which was not true. Yesterday, this message was correct, either because it's been fixed in the meantime, or because it's the 2nd time in a row I configured for GTK (with a maintainer-clean inbetween all builds).

Nothing in configure regarding GTK detection has been changed in years. You probably didn't have pkg-config in the PATH the first time. When this happens, please check config.log and see if you can find any reason in there.

The scroll bar always suggests there is more to come, when in fact the bottom of the buffer is already displayed. This seems to be related to the fact that the last line can be scrolled to the top. Only then does the scroll bar hit the bottom. Even after a week this is still very confusing as on all other applications a glance at the toolbar tells you, in what document part you are! Please fix this to be the same as for the Lucid scrollbar.

This behaviour can't be that confusing as the Motif scroll bar up to 21.3 always behaved this way (but not in the current CVS). I've been trying to get the GTK scroll bars to behave for about nine months (off and on), but GTK really does not support a lot of different behaviours. The GTK people have said that they will not change GTK for the sake of Emacs in this regard, since the Emacs behaviour is so uncommon.

So if you have some code to contribute, please send it anytime, I'm getting fed up with the GTK scroll bars.:-) In the mean time, if you need the Lucid behaviour, compile with the native scroll bars.
