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

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

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