Alpha Build

I forget if we used `inline` elsewhere in ECOS, but be aware that the `inline` keyword is not a part of ANSI C (C89). If I recall correctly, the visual studio C compiler will choke. The workaround is to `#define inline __INLINE__` for visual studio. I think if you put gcc into strict ANSI C mode (I forget how to do that), it will require `#define inline __inline` also.

Just something to be aware of, since I know it will show up when Windows users try to compile this code.
