I'd try rawspeed instead of dcraw. Much faster and cleaner code and the latest version supports almost all cameras.

rawspeed won't let you extract the thumbnail. Also, the reason I suggested dcraw is because it's one C file and that makes things a lot easier, especially when compiling to javascript.

If you want to do raw processing then you don't really care about the thumbnails. No idea about the javascript compile process.
