84 # libcrypto.a) is to eliminate dependency on specific run-time,

86 # to achieve just that. Unfortunately on Linux it's impossible
87 # to eliminate the dependency completely for openssl executable
88 # because of getaddrinfo and gethostbyname calls, which can
89 # invoke dynamically loadable library facility anyway to meet
90 # the lookup requests. For this reason on Linux statically
91 # linked openssl executable has rather debugging value than
