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

116 # -static while -static is also a pass-through compiler option (and

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