Subject: [PATCH] Build system: Check for "strtok_r" availability with "-Wall
 -Werror" when using GCC.
MIME-Version: 1.0
Content-Type: text/plain; charset=utf8
Content-Transfer-Encoding: 8bit

Previously, the check was done without "-Werror" which resulted in a
warning and success. When the daemon was later built with "-Werror" set,
that warning would result in an error and abort the build.

Thanks to Aurélien Reynaud for reporting the problem.
