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

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