I, the luatex files, I actually used a slightly different version
(copied from obsdcompat):

   /*  fix for non-gcc compilation: */
   #if !defined(__GNUC__) || (__GNUC__ < 2)
   # define __attribute__(x)
   #endif /* !defined(__GNUC__) || (__GNUC__ < 2) */

(I added Jerome to the CC list)

Best wishes,
