That's nasty. Why? You know, in Xinerama.h, there's in fact short:

typedef struct {
   int   screen_number;
   short x_org;
   short y_org;
   short width;
   short height;
} XineramaScreenInfo;

I don't know what exactly happens in C integer comparison, but as far
as I tested the other day, it's harmless. No? (These short values
are accessed in "find-head" in src/functions.c.)
