After upgrading to 17.11, I noticed some of my libc+lwip using programs have started logging many warnings like:
pthread_main_np_int: pthread_main_np called, not implemented
This is observed with a fresh checkout (under x86_32/nova); so, I presume the cause is distinct from the similar warnings noted in #2312.
Possibly related (?), during build, there were also quite a few warnings like:
libports/src/lib/libc_lwip/plugin.cc:284:31: warning: âGenode::Env_deprecated* Genode::env()â is deprecated [-Wdeprecated-declarations] Genode::destroy(Genode::env()->heap(), context(fdo));
The programs actually seem to work, but the logs are "overly colorful".
Perhaps there is some initialization that needs to be done differently? Any diagnostic hints appreciated.

I'm not sure but I expect this warning is caused by the FreeBSD resolv library, which for some reason tries to intelligently apply pthread-based multi threading when resolving DNS names.

This warning is unrelated and will disappear after our current lwip/lxip rework is finished. It only hints that this code uses a deprecated but still functional feature of the Genode API.
