Detect setenv/unsetenv; skip main/base_environ test if we can't fake them. Previously, we assumed that we would have setenv/unsetenv everywhere but WIN32, where we could fake them with putenv. This isn't so: some other non-windows systems lack setenv/unsetenv, and some of them lack putenv too. The first part of the solution, then, is to detect setenv/unsetenv/ putenv from configure.in, and to fake setenv/unsetenv with putenv whenever we have the latter but not one of the former. But what should we do when we don't even have putenv? We could do elaborate tricks to manipulate the environ pointer, but since we're only doing this for the unit tests, let's just skip the one test in question that uses setenv/unsetenv.
