I have created an sdl2 devpack with offline documentation. it can be downloaded from the bottom of my winsender project page. http://winsender.sourceforge.net/
Would some of you admins mind reviewing/commenting on it (the devpack) before I post it in the repository. I have tested it with orwell dev-cpp gcc 32bit version, and it seems to work ok but YMMV. I'm unsure how to handle linking with a library which has the same name for 32 or 64bit versions, so haven't even tried that.
