Tags: patch

When I use gcc 14 with -std=gnu99 -Wpedantic I get lots of warnings of
the form

 warning: ISO C99 does not support ‘_Noreturn’ [-Wpedantic].

To avoid those warnings, I propose to use __attribute__ ((__noreturn__))
instead.

You're welcome. It's not that much work, as I can run 
'admin/merge-gnulib' in the Emacs source directory to do most of Gnulib 
importation automatically. Closing the bug report.
