99 # /<xxx> passed through to the compiler. Unix-style options beginning
100 # with a '-' or '+' are recognized, as well as Windows-style

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

107 # -static while -static is also a pass-through compiler option (and
108 # as such is limited to environments where it's actually
109 # meaningful), it triggers a number configuration options,

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