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