This applies to the original code (xgalaga-2.1.1.0), not this port SDL, where that...
Thanks. I've moved the source tree to github a while ago (https://github.com/frank-zago/xgalaga-sdl/)....
Added alt+enter doc.
Support fullscreen for sdl2.
Fixed potential memory leak.
Updated some autoconf files.
Added --enable-sdl2 configure option.
Rename configure.in to configure.in
