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