101 # /<xxx> passed through to the compiler. Unix-style options beginning
102 # with a '-' or '+' are recognized, as well as Windows-style
103 # options beginning with a '/'. If the option contains arguments
104 # separated by spaces, then the URL-style notation %20 can be
105 # used for the space character in order to avoid having to quote
106 # the option. For example, -opt%20arg gets expanded to -opt arg.

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