Ah, right, good catch.  Our XLIB_* "trick" from include/{pre,post}x.h 
(which had been duplicated in 
extensions/source/plugin/inc/plugin/unx/plugcon.hxx prior to 
<http://cgit.freedesktop.org/libreoffice/core/commit/?id=15c609f33da44c24e1d0cf19670b0da43738ce0c> 
"Use prex.h/postx.h").  Should go away once 
<https://bugs.freedesktop.org/show_bug.cgi?id=82577> "get rid of prex.h 
/ postx.h wrapper headers" is fully fixed.
