Add a patch for openssl to fix some breakage that happens when compiled with gcc 4.2.0 Note: this does not cover all instances, but it will at least compile.
If the broken parts are reached at run time, the program will crash. I wonder whose stupid idea it was to intentionally(!) make programs segfault when they hit something that *might* be unsafe to use. Patch taken from http://www.mail-archive.com/openssl-dev@openssl.org/msg22667.html SVN-Revision: 7764
