Comment (by carter):

 oh, the older apple clang was the Wrong output

 the august 21st apple clang behaves as follows (correctly I think)

 {{{
 carter ~ » clang -E -undef -traditional -o - -
 #define FOOBAR(a) test(a, # a)
 FOOBAR(xyz)
 ^D

 # 1 "<stdin>"
 # 1 "<built-in>" 1
 # 1 "<built-in>" 3


 # 1 "<command line>" 1
 # 1 "<built-in>" 2
 # 1 "<stdin>" 2

 test(xyz, # xyz)

 }}}

 YAY
