70 # -<xxx> +<xxx> compiler options are passed through
71 # -static while -static is also a pass-through compiler option (and
72 # as such is limited to environments where it's actually
73 # meaningful), it triggers a number configuration options,
74 # namely no-dso, no-pic, no-shared and no-threads. It is
75 # argued that the only reason to produce statically linked
76 # binaries (and in context it means executables linked with
77 # -static flag, and not just executables linked with static
78 # libcrypto.a) is to eliminate dependency on specific run-time,
79 # a.k.a. libc version. The mentioned config options are meant
80 # to achieve just that. Unfortunately on Linux it's impossible
81 # to eliminate the dependency completely for openssl executable
82 # because of getaddrinfo and gethostbyname calls, which can
83 # invoke dynamically loadable library facility anyway to meet
84 # the lookup requests. For this reason on Linux statically
85 # linked openssl executable has rather debugging value than
88 # DEBUG_SAFESTACK use type-safe stacks to enforce type-safety on stack items
89 # provided to stack calls. Generates unique stack functions for
