92 # argued that the only reason to produce statically linked
93 # binaries (and in context it means executables linked with
94 # -static flag, and not just executables linked with static
95 # libcrypto.a) is to eliminate dependency on specific run-time,
96 # a.k.a. libc version. The mentioned config options are meant
97 # to achieve just that. Unfortunately on Linux it's impossible
98 # to eliminate the dependency completely for openssl executable
99 # because of getaddrinfo and gethostbyname calls, which can
100 # invoke dynamically loadable library facility anyway to meet
101 # the lookup requests. For this reason on Linux statically
102 # linked openssl executable has rather debugging value than
103 # production quality.
