    Fixed bug #176 · dfa643c3
    Sam Lantinga authored
    [I'm fixing this for the public headers, but I'm not going to bother for the SDL library code (yet)]
    
    To clarify: Normaly, GCC (or, to be precise, the preprocessor) will ignore
    this, and compile the code happily. However, one can specify -Wundef to get a
    warning about this.
    
    One can probably argue whether to consider this a bug or not; but I think that
    (a) from a semantic point of view, using "#if FOO" when FOO is not defined is
    strange, and (b) since it is possible to trigger a warning about this, and a
    trivial fix exists, it should be corrected.
    
    I can think of two alternative patches, BTW:
    1) Simply use #define HAVE_FOO 0, instead of not defining HAVE_FOO at all
    2) Change
      #if HAVE_FOO
    to
      #if HAVE_FOO+0
    which always does the right thing.
    
    But I think I still prefer the attached patch :-).
