If I compare how my llvm-gcc42 package builds against
the llvm package files, I find...

g++ -c -g -O2 -mdynamic-no-pic -DIN_GCC -W -Wall -Wwrite-strings -pedantic -Wno-long-long -Wno-variadic-macros -Wmissing-format-attribute -mdynamic-no-pic -DHAVE_CONFIG_H -Wno-unused -DTARGET_NAME=\"x86_64-apple-darwin10.3.0\" -frandom-seed=0 -DNDEBUG -I. -I. -I../../llvm-gcc4.2-2.7.source/gcc -I../../llvm-gcc4.2-2.7.source/gcc/. -I../../llvm-gcc4.2-2.7.source/gcc/../include -I../../llvm-gcc4.2-2.7.source/gcc/../libcpp/include -I/sw/include  -I../../llvm-gcc4.2-2.7.source/gcc/../libdecnumber -I../libdecnumber -I/sw/lib/llvm/include -I/sw/include -DENABLE_LLVM -I/sw/lib/llvm/include  -D_DEBUG -D_GNU_SOURCE -D__STDC_LIMIT_MACROS -D__STDC_CONSTANT_MACROS   -I. -I. -I../../llvm-gcc4.2-2.7.source/gcc -I../../llvm-gcc4.2-2.7.source/gcc/. -I../../llvm-gcc4.2-2.7.source/gcc/../include -I../../llvm-gcc4.2-2.7.source/gcc/../libcpp/include -I/sw/include  -I../../llvm-gcc4.2-2.7.source/gcc/../libdecnumber -I../libdecnumber -I/sw/lib/llvm/include ../../llvm-gcc4.2-2.7.source/gcc/llvm-main.cpp -o llvm-main.o

where in ../../llvm-gcc4.2-2.7.source/gcc/llvm-main.cpp, we have...

#include "llvm/Support/ErrorHandling.h"
#include "llvm/Support/PrettyStackTrace.h"

Shouldn't dragonegg be doing the same...providing
explicit paths from what 'llvm-config --includedir'
returns? Where exactly are some of these headers supposed
to be coming from in llvm-cache.h?

#include "config.h"
#include "system.h"
#include "coretypes.h"
#include "target.h"
#include "tree.h"

Shouldn't some of these have explicit paths like...

#include "llvm/Config/config.h"

or

#include "llvm/Target/target.h"

as is the case in llvm-gcc4.2?
