If you can read the gdb sources, you can also debug it. I speak from
experience, and I'm really not a C expert. It does take a while before
you can find your way in the sources, but the same goes for any big
It's obvious that if gdb were written in Pascal, more Pascal
programmers could easily contribute to it. But I personally do not
consider that downside big enough to rewrite the whole thing from
scratch in Pascal (at least not for Mac OS X and Linux; and other
people are obviously free to spend their time however they like).

Not at that time (I didn't know C at all in 1997).

It's true that the first build takes a long time (especially if you,
like me, build it on a network volume). But after that the incremental
builds don't take that long.
