Hi,
The right thing to do would be to check the return value, so I vote that
we do that. We should be doing that anyway (regardless of glibc
attributes).

Yes.

Disabling -Werror is not an option imo.

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.

    Hi,

    I'm a developper of the OSCAR Cluster opensource software and I4m in
    the process of integrating naemon in se supported things that can be

    For that, I'm integrating naemon into the oscar build system and
    while it works fin on fedora-20, it fails to build on centos-6 with
    the following errors.

    Can this be fixed for next release? (either by disabling -Werror on
    centos6 or by fixing the warning by not ignoring the return code).

    Best regards.
