+ md5, sha1, sha256, sha512: add 'auto', and a way to specify default
+ * m4/gl-openssl.m4 (gl_CRYPTO_CHECK):
+ Add support for a new option, --with-openssl=auto, which causes
+ the library to be used if available and silently ignored if not.
+ Add support to allow allow configure.ac to specify its own
+ default, by setting with_openssl_default before invoking gl_INIT.
