[Message part 1 (text/plain, inline)]

Tags: patch

For some time I have ported Emacs to C89 whenever developers 
inadvertently change the mainline C code to use features like 
declarations-after-statements that C89 prohibits.  It's time for me to 
stop doing this job, as it's no longer useful.  As far as I know, no 
current Emacs target lacks a compiler that supports the relevant 
features.  GCC has supported the features for many years, even decades, 
and key GNU packages such as Coreutils have assumed them for quite some 
time.

To help move this along and to simplify maintenance a bit, I would like 
to install the attached patches into the trunk.  We don't need wholesale 
changes to rewrite Emacs's C code to use C99 features, but on the other 
hand we no longer need to keep porting to C89 and these minimal changes 
will help remind us of that.

The first attached patch is the main one.  The second patch is 
automatically generated by 'admin/merge-gnulib'.
