113 # separated by spaces, then the URL-style notation %20 can be
114 # used for the space character in order to avoid having to quote

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