commit 0494421c858aefbdf544ead22b6037b4877342da
Author: Chris Feng <address@hidden>
Commit: Chris Feng <address@hidden>

    Eliminate a compile warning with `xcb:deftypealias'
    
    * xcb-types.el (xcb:deftypealias): Use variable property instead of
    `defvaralias'/`indirect-variable' to store the fundamental type.
