Confirmed, but I do not know this does not cause a failure on most other targets even with --enable-
werror.

[Bug c/14999] [3.5 Regression] Build failure in stage2: unused parameter 'fndecl'

Looks like targeting alphaev56-unknown-linux-gnu, the function, fold_builtin_cabs, is too 
big to inline so it is emitted instead which causes this warning to show up, there is 
another bug which I will find/file:
static int t(int i)
{
  return 0;
}
int tt()
{
  return t(0);
}
