Yeah, xkbcomp's utils.h is rather messy all around - but as I looked
at cleaning it up I saw so many things that needed fixing, I just
punted for now.   It could use reformatting and dropping unused macros
(it defines 1-10 argument variants of each macro from the days before
 varargs macros, but many of those variants are never used).
