Hello all

Thanks for the good work on emacs (which I am using since before 1990, 
the year I defended my PhD in Paris)

I git cloned in /usr/src/Editors/emacs then

'./configure'  '--program-suffix=-trunk' 'CFLAGS=-O2 -g'

and the build fails (repeatedly)

When gcc is version 11.2 from Ubuntu

Hope this helps

Cheers
