compiling C++ in the toolchain.

[Peter Nijs]

In which file of the toolchain can I configure "make" to use arm-angstrom-
linux-gnueabi-g++ instead of arm-angstrom-linux-gnueabi-gcc? I can't find it 
in any file that is not made by om-conf. I wonder if it's an argument of om-
conf. #om-conf --help and #man om-conf don't do anything useful.
