yaSSL-0.9.7 library bundled. BUILD/Makefile.am: compile-pentium-debug-yassl added to distribution. Makefile.am: Added yassl_dir to SUBDIRS. It contains path to yassl distribution if --with-yassl specified. It is empty otherwise. configure.in: yaSSL CHECK-function call. extra/Makefile.am: yaSSL added to distribution. include/violite.h: YASSL_MYSQL_COMPATIBLE macro must be defined to make yassl headers compatible.
