(svn r17705) -Fix: [OSX] Re-enable signal handling on OSX 10.3.9. Trying to link with an undefined symbols that lives in the system library seems to confuse the loader on 10.3.9. Use a different function to circumvent it.

/*
* OSX 10.3.9 has blessed us with a signal with unlikable side effects.
* The most problematic side effect is that it makes OpenTTD 'think' that
* it's running on 10.4.0 or higher and thus tries to link to functions
* that are only defined there. So now we'll remove all and any signal
* handling for OSX < 10.4 and 10.3.9 works as it should at the cost of
* not giving a useful error when savegame loading goes wrong.
