75# argued that the only reason to produce statically linked
76# binaries (and in context it means executables linked with
77# -static flag, and not just executables linked with static
78# libcrypto.a) is to eliminate dependency on specific run-time,
79# a.k.a. libc version. The mentioned config options are meant
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
85# linked openssl executable has rather debugging value than
