Can you move the getenv() call down to the point where the result is
actually used so we don't have to worry about its value going stale[1]
by some intervening call to getenv(), setenv(), unsetenv() or
putenv()? Alternately, move the check against "yes" up here and assign
it to a boolean (int) which you consult later.
Ditto for the other patches. Thanks.
