With current CVS I get a bootstrap error in cp/decl.c on Linux/AMD64:

cc1: warnings being treated as errors
/cvs/gcc/gcc/cp/decl.c: In function 'reshape_init':
/cvs/gcc/gcc/cp/decl.c:4162: warning: 'max_index_cst' may be used uninitializedin this function
make[2]: *** [cp/decl.o] Error 1

The code is basically:

  HOST_WIDE_INT max_index_cst;
  if (sized_array_p)
    /* HWI is either 32bit or 64bit, so it must be enough to represent the
	array size.  */
    max_index_cst = tree_low_cst (max_index, 1);

  for (index = 0;
       *initp && (!sized_array_p || index <= max_index_cst);
       ++index)

So, this looks like some wrong warning - but we fix it somehow.
