82 # libcrypto.a) is to eliminate dependency on specific run-time,
83 # a.k.a. libc version. The mentioned config options are meant
84 # to achieve just that. Unfortunately on Linux it's impossible
85 # to eliminate the dependency completely for openssl executable
86 # because of getaddrinfo and gethostbyname calls, which can
87 # invoke dynamically loadable library facility anyway to meet
88 # the lookup requests. For this reason on Linux statically
89 # linked openssl executable has rather debugging value than
