I've only looked at the C version, but I like what I see, I've been using it to learn C to help when making a compiler, but it's funny, most compiler books are for other languages. I'd figure a lot of compilers would be written in C, but guess not.
Most real compilers are written in C, but it's not the best language to teach compiler-writing in, since many students don't know C and it's a difficult enough subject without having to teach C too. That said, the Dragon Book is still the One True Compilers Text.
It's never true that you shouldn't study something, but yeah, that's going to be rough. I think I recall you mentioning being familiar with Scheme in another thread, in which case you might try Essentials of Programming Languages followed by Lisp in Small Pieces.
