I like the ^Z part.  I thought the [1-9] should be [1-9]+, but then I
realized that the ".*" in front of it takes care of classes that are
longer than 9 characters.

The [a-zA-Z_][a-zA-Z0-9_]+ does not accept 1-character classes.  How about
[a-zA-Z_][a-zA-Z0-9_]*.

GNU C++ has an "-fdollars-in-identifiers" flag, so you have to accept '$'
as an alphabetic character.

  ^_Z.*[1-9][a-zA-Z_$][a-zA-Z0-9_$]*D[0-2]Ev$

Watch out -- dependency creep.

If it were me, I would go ahead with the v3 abi stuff and get something
in with an r.e. that works most of the time.  Today's gdb works 0%
of the time in this case.  Then pick up the ternary search trees as a
separate project.  But that's just me.

(I read up on ternary search trees last night.  They look like an awesome
data type to replace the hash tables.)
