MySQL Bugs: #72019: Is my server 32 bit or 64 bit?

Description: I was asked by a user "How do I know if the server I am connected to is 32 bit or 64 bit server?". I find the server variable "version_compile_os" explained in http://dev.mysql.com/doc/refman/5.6/en/server-system-variables.html#sysvar_version
