# -static       while -static is also a pass-through compiler option (and
#               as such is limited to environments where it's actually
#               meaningful), it triggers a number configuration options,
#               namely no-dso, no-pic, no-shared and no-threads. It is
#               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.

# -DPEDANTIC complements -pedantic and is meant to mask code that
# is not strictly standard-compliant and/or implementation-specific,
# e.g. inline assembly, disregards to alignment requirements, such
# that -pedantic would complain about. Incidentally -DPEDANTIC has
# to be used even in sanitized builds, because sanitizer too is
# supposed to and does take notice of non-standard behaviour. Then
# -pedantic with pre-C9x compiler would also complain about 'long
# long' not being supported. As 64-bit algorithms are common now,
# it grew impossible to resolve this without sizeable additional
# code, so we just tell compiler to be pedantic about everything
# but 'long long' type.
