74# argued that the only reason to produce statically linked
75# binaries (and in context it means executables linked with
76# -static flag, and not just executables linked with static
77# libcrypto.a) is to eliminate dependency on specific run-time,
78# a.k.a. libc version. The mentioned config options are meant
79# to achieve just that. Unfortunately on Linux it's impossible
80# to eliminate the dependency completely for openssl executable
81# because of getaddrinfo and gethostbyname calls, which can
82# invoke dynamically loadable library facility anyway to meet
83# the lookup requests. For this reason on Linux statically
84# linked openssl executable has rather debugging value than
85# production quality.
