Bootstrap failure on Darwin 6.0

[Timothy J. Wood]

  Checked out from the mainline (of FSF repository, not Darwin's):

export CC='cc -no-cpp-precomp'
./configure --prefix=/Users/Shared/$USER/gcc3-vanilla 
--enable-languages="objc c++"
make bootstrap

xgcc: Internal error: Illegal instruction (program cc1)


  The system crash log says that this is infinitely recursing:
