111 # used for the space character in order to avoid having to quote

120 # binaries (and in context it means executables linked with
121 # -static flag, and not just executables linked with static
122 # libcrypto.a) is to eliminate dependency on specific run-time,
123 # a.k.a. libc version. The mentioned config options are meant
124 # to achieve just that. Unfortunately on Linux it's impossible
125 # to eliminate the dependency completely for openssl executable
126 # because of getaddrinfo and gethostbyname calls, which can
127 # invoke dynamically loadable library facility anyway to meet
128 # the lookup requests. For this reason on Linux statically
129 # linked openssl executable has rather debugging value than
130 # production quality.
