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

87 # provided to stack calls. Generates unique stack functions for
