Yes.

Well...

Warnings are warnings rather than errors because they are not, in fact, 
errors. Errors, on the other hand, are errors, which makes them 
different from warnings. -Werror is a simple way to say "break this very 
simple concept".

There's a ton of compilers and compiler versions and things they might 
or might not warn for - correctly or incorrectly[0] - before doing the 
right thing anyway: it was a warning, not an error, after all. 
Guaranteeing that nobody will see a warning is hard and boring, and 
-Werror antagonizes compiler developers who add new and helpful checks.

For development, we should always strive to build with (and make it hard 
to disable) as many of
   -Wall -Wextra -Werror -pedantic -fstack-protector-all \
   -D_FORTIFY_SOURCE=2 -Deasy-mode -fhelp-me-please
as possible, because writing C is hard, and I most certainly don't trust 
myself to do it unassisted.

However, it's hard to resist the argument that tarballs intended for 
public consumption should probably try to do what said public want to 
them to, i.e. build and work.

[0] Compilers are buggy, too. While in this case, the compiler is right,
     I remember when code I wrote failed to build with -Werror due to
     https://gcc.gnu.org/bugzilla/show_bug.cgi?id=36750 where GCC'd warn
     that my code followed the standard and suffered from no undefined
     behavior whatsoever - gee, thanks.
