 | #               interfaces deprecated as of the specified OpenSSL version. | 
 | # | 
 | # no-hw-xxx     do not compile support for specific crypto hardware. | 
 | #               Generic OpenSSL-style methods relating to this support | 
 | #               are always compiled but return NULL if the hardware | 
 | #               support isn't compiled. |

 | # [no-]threads  [don't] try to create a library that is suitable for | 
 | #               multithreaded applications (default is "threads" if we | 
 | #               know how to do it) | 
 | # [no-]shared	[don't] try to create shared libraries when supported. | 
 | # [no-]pic      [don't] try to build position independent code when supported. | 
 | #               If disabled, it also disables shared and dynamic-engine. |

 | # no-dso        do not compile in any native shared-library methods. This | 
 | #               will ensure that all methods just return NULL. | 
 | # no-egd        do not compile support for the entropy-gathering daemon APIs | 
 | # [no-]zlib     [don't] compile support for zlib compression. | 
 | # zlib-dynamic	Like "zlib", but the zlib library is expected to be a shared | 
 | #		library and will be loaded in run-time by the OpenSSL library. | 
 | # sctp          include SCTP support | 
 | # enable-weak-ssl-ciphers | 
 | #               Enable weak ciphers that are disabled by default. This currently | 
 | #               only includes RC4 based ciphers. | 
 | # 386           generate 80386 code in assembly modules | 
 | # no-sse2       disables IA-32 SSE2 code in assembly modules, the above | 
 | #               mentioned '386' option implies this one | 
 | # no-<cipher>   build without specified algorithm (rsa, idea, rc5, ...) | 
 | # -<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 |
