 Looks like that's a problem:
 
 $ cat baz.c
 #ifndef __GCC_HAVE_SYNC_COMPARE_AND_SWAP_4
 #error "compiler has atomic ops, but doesn't define __GCC_HAVE_SYNC_COMPARE_AND_SWAP_4"
 #endif
 
 $ gcc -o baz baz.c 
 baz.c:2:2: error: #error "compiler has atomic ops, but doesn't define __GCC_HAVE_SYNC_COMPARE_AND_SWAP_4"
  #error "compiler has atomic ops, but doesn't define __GCC_HAVE_SYNC_COMPARE_AND_SWAP_4"
