As mentioned earlier, projects should not use -Werror when configuring, 
for several reasons (this is just one). After you mentioned rsync was 
using something like -Werror I sent in a patch to the rsync folks, and 
rsync has been fixed:

https://github.com/WayneD/rsync/commit/9a3449a3980421f84ac55498ba565bc112b20d6c

What other projects are doing it? They should be fixed too, regardless 
of whether we change Autoconf here.

As for Autoconf, if we're going to make this change at all, we should do 
it fully. Something like the attached patch, perhaps. I haven't 
installed it.
