So, shortly, when setting h_errno value, right ?

That's a workaround, as h_errno *should* works.
netdb.h define is as a macro:
#define h_errno (*(_h_errnop()))
Something is wrong about our h_errno TLS code, I guess.
Will look into it (src/kits/network/libnet/compat.c and headers/posix/
netdb.h)...
