* Cleaned up some useless and redundant preprocessor definitions.
* Fixed the win build so that it correctly uses the mysql lib it built from the sources.
* Note that you still need to use 8615_mysql_openssl_libs.zip for the OpenSSL binaries.
* Also note that Win x64 build from the existing VS files is still fubar (mysql lib...).
