[SDL] Scrap for OSX (copy and paste)

[E. Wing]

So a #include in a file is equivalent to copying the entire contents
of the file you are including and pasting it in the calling file.

So if you #include a .m file from a .c file, you've effectively just
changed your pure C file to Obj-C. (Same goes for C++.)

This is probably why you are getting errors. You are compiling
Objective-C code as C instead of Obj-C.


As I said, my recommendation is that your main.c should only #include
the public header file (scrap.h) which is a pure C interface. Then
compile scrap.c or scrap_OSX.m depending on the platform.
