Subject: [PATCH] Fix to unbreak SDL_GetSystemRAM() on FreeBSD

Marcus von Appen

Revision c47ae79f0de8 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.
