Added macro so that targetconditionals.h isn't included when compiling from versions of Mac OS X earlier than 10.3 (the header file doesn't exist there). Instead, it is just assumed that you want to compile for Mac OS X rather than iPhone ... a fine assumption since you need 10.5 to compile for iPhone.

The test programs in this directory tree are for demonstrating and
testing the functionality of the SDL library, and are placed in the
public domain.
