From 2ab442623e689532910b34ff0dbbc2167da02330 Mon Sep 17 00:00:00 2001

Subject: [PATCH] fix musl compatibility (missing function prototypes)
inet_net_pton is already compiled, but no prototype is provided.
res_hnok is provided by the compatibility layer in libasr.
These fixes avoid warnings about implicit function declaration.
Fixes #758
