 // HACK: we need this #define in place before npapi.h is included for
 // plugins to work. However, all sorts of headers include npapi.h, so
 // the only way to be certain the define is in place is to put it
 // here.  You might ask, "Why not set it in npapi.h directly, or in
 // this directory's SConscript, then?"  but it turns out this define
 // makes npapi.h include Xlib.h, which in turn defines a ton of symbols
