+/*
+ * <netdb.h> for the MontaukOS git port.
+ *
+ * The port builds NO_IPV6=1, so git resolves names through gethostbyname()
+ * and getservbyname() rather than getaddrinfo(). Both fail here: MontaukOS
+ * resolves DNS inside the kernel network stack, and no userspace resolver
+ * interface is exposed. `git clone git://host/repo` therefore reports that it
+ * cannot look up the host. getaddrinfo() is still declared because
+ * git-compat-util.h references the types unconditionally.
+ *
+ * Implementations in montauk-compat.c.
