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

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

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