Does LCC build abstract syntax tree?

I find a paper (http://drhanson.s3.amazonaws.com/storage/documents/
lean.pdf) that saying (on page 21)  that one of mistakes is LCC
doesn't have an AST.
I am confused here - isn't the Tree struct defined in C.h the AST?
There is no nodes in that tree build to represent none terminals, and
it looks to me the exact kind of AST...

Could some one on the list please answer my (possibly stupid) question?

The link I posted is broken due to some reasons.. the paper can be
found on the LCC site http://www.cs.princeton.edu/software/lcc/doc/index.html

cross-build ports?
With tinderbox (ports-mgmt/tinderbox) I can build ports for several releases / branches, for example FreeBSD 6.3-stable and FreeBSD 7.x-stable on the same machine, which is nice. But I haven't found a way to cross-build ports (eg. build packages for i386 on an amd64 machine) with tinderbox. Is this possible? If not, is therr anuy other way to cross-build ports in FreeBSD? I have googled a while, but didn't find anything. Why do I want to cross-build ports? Because I have a new (and fast) amd64 machine, and several older i386 machines. The i386 machines are sloow, so i...

Stability of decision trees
Hi there, I need your help to a new problem that i encounter. I have create some decision trees and get results. I sample my data every time, having test and training set. Sometimes I get a different decision tree, in means of changing the order of features in the tree nodes, or increase the tree nodes. What i need are 1. Is there any measure for good decision tree stability? 2. Is there any method to improve trees stability? 3. If yes is there matlab code any relative theory?

Lisp Syntax

Variable Declaration syntax?

Database Abstraction Layer And/Or ORM

I have found a number of options such as those listed here: http://wiki.python.org/moin/HigherLevelDatabaseProgramming I'm not looking for a holy war based on whether a DAL/ORM *should* be used, and/or if it is preferred over direct access to the database API layer. I understand that can be a lengthy discussion. I would just like to see if there is a common 'preferred choice' in the area. I am coding an application around...

Collapse tree menu using dom???
I am confused on childNodes or children. When you have nested lists, I would think it would all be one list in the Dom, this doesn't seem to be the case. So how do you traverse an unordered list? Any help appreciated. John In the below script, I can expand and contract the nodes when clicked on, but I want the menu to close all other siblings to the node clicked so that only one sub menu option is expanded at one time. If the node display is being set to none, I would also like it to collapse all the sub nodes. <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN&qu...

Build 10022
Enrico updated svn with Build 10022 which (supposedly) pacified warnings somewhere. However, the MinGW build still failed with the same warnings I previously posted. I'll wait for a more convenient time to make another build btw, the build sequence terminates after the warning, and when I later take a look at the screen, it shows the warning display painted *over* the build sequence which itself is halted at the start of the 'Contrib' sequence. When I 'X' out of this warning, the 'Contrib' sequence continues to completion. But ma...
