SDL 1.2 actually defaults to vsync off anyway, plus older version of SDL don't have the setting so it was causing issues building on some old systems.

Adds support for building with GCC 2.95.
GCC 2.95's C mode, even with
-std=gnu9x, doesn't support mixed declarations and code, which makes it impossible to adapt butterscotch to support it without major effort. It would basically be a full C89 conversion, and would be a monumental diff. This is unacceptable.The solution was to target GCC 2.95's C++ mode. C++ has supported mixed declarations and code for much longer, so I just made the changes required to build with
g++ -fpermissive. You must use-fpermissivebecause otherwise GCC will error whenever you implicitly cast avoid *to another pointer type.
