yep, and that should be sufficient.  in the pre-relocation stages, you can only 
have one active getenv() at a time, but that isn't anything new, and in this 
particular case, it's fine.

if people need an explicit getenv_ulong_r() in the future, we can wait for 
someone else to propose that.  but i think it unlikely.
