# know how to do it)

# If disabled, it also disables shared and dynamic-engine.
# no-asm do not use assembler

# -<xxx> +<xxx> compiler options are passed through
# -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.
#
# DEBUG_SAFESTACK use type-safe stacks to enforce type-safety on stack items
# provided to stack calls. Generates unique stack functions for
# each possible stack type.
# BN_LLONG use the type 'long long' in crypto/bn/bn.h
# RC4_CHAR use 'char' instead of 'int' for RC4_INT in crypto/rc4/rc4.h
# Following are set automatically by this script
#
# MD5_ASM use some extra md5 assembler,
# SHA1_ASM use some extra sha1 assembler, must define L_ENDIAN for x86
# RMD160_ASM use some extra ripemd160 assembler,
# SHA256_ASM sha256_block is implemented in assembler
# SHA512_ASM sha512_block is implemented in assembler
# AES_ASM AES_[en|de]crypt is implemented in assembler
# Minimum warning options... any contributions to OpenSSL should at least get
# past these.
# DEBUG_UNUSED enables __owur (warn unused result) checks.
# -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.
