78# libcrypto.a) is to eliminate dependency on specific run-time,

80# to achieve just that. Unfortunately on Linux it's impossible
81# to eliminate the dependency completely for openssl executable
82# because of getaddrinfo and gethostbyname calls, which can
83# invoke dynamically loadable library facility anyway to meet
84# the lookup requests. For this reason on Linux statically
