Artifact 9e35aba1440766a7592fbb87fb8ac7dba3ac0a35:

• File configure.ac — part of check-in [02f5cea2da] at 2011-09-08 01:47:17 on branch trunk — CACKey 0.6.2

  Updated to include sha1.c, md5.c, and asn1-x509.c in the cackey.c translation unit so that these symbols never get exported and conflict with existing programs

  Updated to try harder to remove and weaken symbols from shared object (user: rkeene, size: 3318) [annotate] [blame] [check-ins using]
