I did that already in the current CVS, as I said in my last mail.
It should finish in about 21 seconds on your machine now.

We are actually putting deprecated functions back in.
This one should be easy enough; simply call append().

I admit I was confusing in my choice of words.
By "fast" I didn't mean the speed of the compiler (which I don't care about), 
but the speed of the code produced by the compiler.  Here, gcj will beat 
jikes for the simple reason that gcj produces native machine code while jikes 
produces java bytecode.
As far as compilers producing Java bytecode go, Sun's javac is your best
bet from my experience at this point.
