# /<xxx> passed through to the compiler. Unix-style options beginning
|

# with a '-' or '+' are recognized, as well as Windows-style
|

|
# separated by spaces, then the URL-style notation %20 can be
|
|
# used for the space character in order to avoid having to quote

|

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