73# argued that the only reason to produce statically linked

76# libcrypto.a) is to eliminate dependency on specific run-time,
77# a.k.a. libc version. The mentioned config options are meant
78# to achieve just that. Unfortunately on Linux it's impossible
79# to eliminate the dependency completely for openssl executable
80# because of getaddrinfo and gethostbyname calls, which can
81# invoke dynamically loadable library facility anyway to meet
82# the lookup requests. For this reason on Linux statically
83# linked openssl executable has rather debugging value than
84# production quality.
