Fix to unbreak SDL_GetSystemRAM() on FreeBSD Marcus von Appen Revision eecbcfed77c9 of the SDL hg repo introduces the new SDL_GetSystemRAM() function, which breaks the build on FreeBSD. Find attached a patch, which unbreaks the build and also should (for most cases) properly implement the sysctl support it.
