82 # libcrypto.a) is to eliminate dependency on specific run-time,
83 # a.k.a. libc version. The mentioned config options are meant
84 # to achieve just that. Unfortunately on Linux it's impossible
85 # to eliminate the dependency completely for openssl executable
86 # because of getaddrinfo and gethostbyname calls, which can
87 # invoke dynamically loadable library facility anyway to meet
88 # the lookup requests. For this reason on Linux statically
89 # linked openssl executable has rather debugging value than

2771 perform build related tasks. The databanks are:
2773 %config Configured things.
2774 %target The OpenSSL config target with all inheritances
2776 %disabled The features that are disabled.
2777 @disablables The list of features that can be disabled.
2778 %withargs All data given through --with-THING options.
