Description

I've started compiling, and cleaning up traffic-server from trunk with clang, with this config:

i.galic@phoenix ~/Projects/asf/trafficserver (svn)-[trunk:989985] % cat config.notnice
#! /bin/sh
#

1. Created by configure

CC="clang"; export CC
CXX="clang"; export CXX
CFLAGS="-fPIC -march=core2 -msse4.1 -D_FORTIFY_SOURCE=2"; export CFLAGS
CXXFLAGS="-fPIC -march=core2 -msse4.1 -D_FORTIFY_SOURCE=2"; export CXXFLAGS
LDFLAGS="Wl,as-needed -Wl,-warn-common"; export LDFLAGS
"./configure" \
"--enable-layout=opt" \
"--with-user=proxy" \
"--with-group=proxy" \
"CC=clang" \
"CFLAGS=-fPIC -march=core2 -msse4.1 -D_FORTIFY_SOURCE=2" \
"LDFLAGS=Wl,-as-needed" \
"CXX=clang" \
"$@"

Until I hit errors that seemed to include templates.
I'm uploading the current patch for you to sanity-check and review. If it makes sense, I suppose it does a bit of a clean-up.
