# libc_ndk.a
# Compatibility library for the NDK. This library contains

# We can't safely statically link things that can only run
# on a certain version of the OS. Examples include
# anything that talks to netd (a large portion of the DNS
# code) and anything that is dependent on the layout of a
# data structure that has changed across releases (such as
# pthread_t).
