105 # separated by spaces, then the URL-style notation %20 can be
106 # used for the space character in order to avoid having to quote
107 # the option. For example, -opt%20arg gets expanded to -opt arg.

110 # -static while -static is also a pass-through compiler option (and
111 # as such is limited to environments where it's actually
112 # meaningful), it triggers a number configuration options,
113 # namely no-pic, no-shared and no-threads. It is
114 # argued that the only reason to produce statically linked
115 # binaries (and in context it means executables linked with
116 # -static flag, and not just executables linked with static
117 # libcrypto.a) is to eliminate dependency on specific run-time,
118 # a.k.a. libc version. The mentioned config options are meant
119 # to achieve just that. Unfortunately on Linux it's impossible
120 # to eliminate the dependency completely for openssl executable
121 # because of getaddrinfo and gethostbyname calls, which can
122 # invoke dynamically loadable library facility anyway to meet
123 # the lookup requests. For this reason on Linux statically
124 # linked openssl executable has rather debugging value than
125 # production quality.
