The latest development version of SDL is available via CVS:

cvs -d :pserver:guest@libsdl.org:/home/slouken/libsdl.org/cvs login

# No password, so just hit enter when prompted for a password

cvs -d :pserver:guest@libsdl.org:/home/slouken/libsdl.org/cvs checkout SDL

When you check a fresh copy of SDL out of CVS, you need to generate

the files used by make by running the "autogen.sh" script, which will

run aclocal, automake, autoconf and then run configure.
