The sys/sysctl.h header is only needed on BSD platforms to get the sysctlbyname() function declaration. On Linux we talk to procfs instead to change sysctls. Unfortunately a legacy sys/sysctl.h header does exist on Linux and including it has recently started triggering a deprecation warning from glibc. Protect its inclusion with a HAVE_SYSCTLBYNAME check instead so that it only gets used on platforms where we need that function declaration. Signed-off-by: Daniel P.
