Hi, sorry for being a bit unclear before.

The patch would just fix llvm-gcc build system to be able to compile  
with both, *llvm build in source directory* and *installed llvm  

Correct include directory can be get with llvm-config --includedir,  
because when llvm-config is excuted from llvm source tree (from  
Release or Debug directory) it will return the include directory of  
source tree (e.g. llvm-2.6svn/include). If llvm-config is called from  
installation path it returns include directory of installed llvm  

I  tried the patch with compiling llvm-gcc with:
- llvm-2.5 source tree build
- installed llvm-2.5 from sources
- apt-get installed debian llvm-2.5 packages.

I will try if the patch works correctly with llvm trunk as well and  
show also the compile commands which were used to configure and  
compile the llvm-gcc.
