You cannot choose to run without Cocoa/ObjC unless you choose to build the
Carbon version of SDL. Getting the Carbon version to work might be painful
(see previous posts on this), and the Carbon version is generally flaky.

I'd recommend using the files SDLMain.m/.h in your project instead (from
the stationary). You can write your application in main.c; you don't have
to write any ObjC code, your code can all be C/C++.

The actual SDL implementation and startup code uses Cocoa/ObjC, which is
why we have this requirement.

>From a programming or performance standpoint, there is no disadvantage to
using Cocoa/ObjC; however, there are issues getting SDL "embedded" into
applications/interpreters that don't link to SDL directly (see previous
posts).
