 I don't known. I have just installed GCC 1.42
(from this mirror: 
  ftp://ftp.cs.univ-paris8.fr/mirrors/ftp.gnu.org/gcc/gcc-1.42.tar.gz )
 and I have seen that it didn't recognize __builtin_constant_p.

 But with ftp://ftp.cs.univ-paris8.fr/mirrors/ftp.gnu.org/gcc/gcc-2.7.2.3.tar.gz
  it works.

 I will try to find other GCC releases.
