For those interested, it's not hard to make gcc transparently invoke
ctfconvert either in response to -g or even -gctf. For example,

Of course, it would be better if there were a way to use libctf
directly...good luck finding a way around the licensing challenges
there. But even with the specs hack the compiler side of the
interface is nice.
Don't hold your breath waiting for Sun's compiler team to release
their source. I suggest doing this work in gcc and then shaming them
into supporting a similar interface.
