-Subject: [PATCH 3/3] Improve check of the sysctl() function
-
-Since sysctl is a deprecated system call, new architectures such as
-ARC don't implement it. In such cases, uClibc installs the
-<sys/sysctl.h> header, but dos not implement the sysctl()
-function. This has the annoying side effect of breaking the sysctl
-detection of radvd, which is purely based on the header file being
-present.
-
-To fix this, this commit adds a check based on the existence of the
-sysctl() function.
