I do not provide a fix because the correct fix is to check for both
setenv/putenv and there declaration. But semantic of setnev/putenv is very
different - setenv() copies it's argument, but putenv() does not (for this
reason I hate setenv - it is asking for memory leaks :-). So, it is not
possible to just replace one with another.

Our system lacks setenv, BTW.
