Oh, it's this bit?
(defcustom gmm-tool-bar-style
(if (and (boundp 'tool-bar-mode)
tool-bar-mode
- (and (fboundp 'display-visual-class)
- (not (memq (display-visual-class)
- (list 'static-gray 'gray-scale
- 'static-color 'pseudo-color)))))
+ (memq (display-visual-class)
+ (list 'static-gray 'gray-scale
+ 'static-color 'pseudo-color)))
'gnome
'retro)
Oops. Looks like I removed the `not' by mistake while I was cleaning up
the foundp test somehow?
That's clearly a regression and should be fixed on the emacs-27 branch,
I think.
