Use 10.5 SDK header files in an attempt to keep us honest and
10.5 compatible. I'd do the same with system libraries, but
the linker gives strange errors when I try that. We also link
against third party libraries from Macports that haven't had
any magic 10.5 compat dust sprinkled over them, so maybe it
isn't very important anyway.
Move the OS X variable section in SConstruct upwards a bit to
have the settings apply to more of the config tests. SCons'
ParseConfig causes problems for the -arch tuples, though, so
the SDL check still isn't quite as comprehensive as it should
be.
Put the XCode project out of its misery.
